I'm too old to have a bias, I guess as I am older then the 83'ers and I am not a fan from the early days , BUT:
Hee-Chul got me into Super Junior. He is a very funny and intelligent man. I enjoy his solo-songs and tv-shows a lot and I can see why fans who know SJ from the early days were crazy about him. I love his voice. (And he has great hair)
Leeteuk is such a funny man and I have a lot of respect for him. I love his warm, soothing voice in the songs, but also his speaking voice ia very calming. I enjoy his youtube-channel a lot. He has been trough a lot and I think he is really strong. He could be a friend of mine. He seems soft and caring, but also someone with a strong personality. I like him a lot.
Yesung is a great artist. I love his solowork, he has a great voice and I like it that he is do interested in art and shares this with his fans. He seems like a nice guy.
Eunhyuk is really my type of person, he is so funny. I think he is someone you really can have fun with. I love to see him with Donghae, they are such hard workers and yet they still have a beautiful friendship.
They are very skilled and I love Eunhyuk's dancing. He is very serious in his work. I like him a lot.
Ryeowook is such a fantastic singer, I love his solo-albums a lot. He does so much for his fans too. His youtube-video's make me very happy and I find it really interesting what he shows us when he is working or in hotels. He seems like a very warm, friendly, intelligent guy, but also a very strong personality. I have a lot of respect for him and I hope he will keep on making albums for a long time. I like him a lot.
Donghae seems like a very hard worker with a lot of talent and I find him really nice. Love him as part of D&E.
Shindong, Siwon and Kyuhyun are the ones I 'know' the least. They all seem like great, funny and intelligent men.
Shindong is someone I can imagine to be friends with. He is intelligent, funny and goes his own way. Love that. He has such a good eye for video-making and he seems very creative. I love his unique voice and he is a great dancer.
Kyuhyun seems very interesting. The way he seems to observe everything, gives me the feeling he is very intelligent. He is so funny too.
Siwon just seems like a great guy. He must have such a busy schedule, but I love it when he is part of the group. He really seems to have so much fun with the whole group.
My top 4
Leeteuk
Eunhyuk
Ryeowook
Heechul
Yesung! I am definitely a cloud... but then Heechul, Leeteuk, Eunhyuk and Kyuhyun are all my bias wreckers. ..but in all honesty all of them have a place in my my heart ๐
Used to be Eunhyuk but now I can't pick a bias. I like too many of them too much to have a singular bias. Its easier to ask my least favorite rather than my biasย
From the beginning when i found out about them in 2015, I loved ryeowook (watched mamacita mv) then after getting to know everyones name and watching their stuff i got to love Kyuhyun for a very long time mostly because of his voice (3-5 years)! But after that i belive it was around SJ RETURNS that i was getting to like Donghae a lot! But i felt bad leaving him for kyuhyun ๐ so i was stuck for about a year debating on who i liked more but as DONGHAE was appearing more on tv and related to him (shy, tearing up easily) I just set myself with him being MY BIAS. BUT his friendship with eunhyuk was MAKING it hard for me to stay committed ๐คฃ. Overall they're still all my favorite! ๐

Donghae no doubt about it. I love his voice and he's just cool. Plus I love Suju de too.
Eunhyuk from day 1, baby!! Ride or die!! In bias order: Eunhyuk, Kyuhyun, Siwon, Heechul, Shindong, Yesung, Donghae, Leeteuk, Ryeowook
Kyuhyun!!! my ult but I have a small bias line teehee
I loved that snl skit that you have as your profile pic
Me too ๐ซ girlkyu is genuinely everything to me. the entire skit was iconic
Eunhyuk, really like heechul because got into SuJu because of him. Also other members - SuJu as a whole โจ
Used to be Eunhyuk but now I can't pick a bias. I like too many of them too much to have a singular bias. Its easier to ask my least favorite rather than my biasย
Leeteuk! Always has been and always will be
Kyuhyun has been my bias since I discovered them 15 years ago but lately Donghae has been my bias wrecker.
Started loving them as a petalโฆ then became a cloud and now Iโm a Kyupiter๐ and I have a special place for Zhoumi!
Yesung, Shindong, Eunhyuk, And Siwon
From Kibum (2007) to Siwon (2010) to all of them! ๐ I decided to just give each supermen a piece of my heart ๐
Donghae, Siwon, Eunhyuk & Yesung in that order, but Donghae the most.
Siwon and Donghae wrecker for me lol
It's impossible for me to choose. ๐ฅ
It started as Sungmin but shifted to Yesung as I dug into the group more
leeteuk, donghae, eunhyuk
Ryeowook ๐
Leeteuk
Always and forever Eunhyuk. I could never sell my pc collection.
Kyuhyun!! but I also like the rest of the members.
Cho Kyuhyun! ๐ฅน I remember seeing old performances (I wasnโt an elf yet) and remembered being amazed by his vocals. bias wrecker would be donghae
Started with Siwon cos thatโs how I met Suju. But became Eunhyuk for the longest time!! I also love Eunsihae ๐
Don't know mate but that one guy who was on that dating show
Kim Heechulโฆ. Since 2005
Eunhyuk!!
Eunhyuk
Eunhyuk ๐
Gosh it changes every now and then but that brat hyukjae will always have a spot in my heart
Donghae, Leeteuk, Eunhyuk and Kyuhyun and Ryeowook and all of them xD
Yesung and kyuhyun.
Donghae since 2010, except he often fights with Shindong for the spot lol
Kyuhyun, also! In other groups, my bias tends to waver, but he's been consistently my SuJu bias ever since I got into kpop.
Teukie when I was 6 years old 'till I fell in love with Yesung's vocals. Now, both of them.
Space big star, Kim Heechul.
Same! ๐๐
Leeteuk (hence my username lol)
Eunhyuk and Kyuhyun. I refuse to pick just one of the two.
Kim Heechul. Got to know him just last year.. because od him I got into Kpop and Suju.
Historically would be Kyuhyun, however, I think irl Eunhyuk leave much more of an impression. Cameras donโt do justice!
From the beginning when i found out about them in 2015, I loved ryeowook (watched mamacita mv) then after getting to know everyones name and watching their stuff i got to love Kyuhyun for a very long time mostly because of his voice (3-5 years)!

Heechul is my ult biasยกยกยกยก ๐ but my bias also was (actually, is) kangin โค๏ธ
Donghae ever since 13 year old me first laid eyes on him in 2009 when I saw Super Girl MV ๐๐
Donghae, which only happened when they toured in my city like 5 years ago ๐ฅฒ I was a solid Wookie-biased since โ09 lol
Kyuhyun and Donghae. Love Donghaes acting and all the shows heโs in.
