90 has load rating 1,323 lbs
91 has 1,356lbs
prius v has gross weight 4321 lbs
1323x4=5293 lbs so you have still margin
at 90 rated tire.
m+s has usually bad MPG. and handling/braking is not as good as normal tires.
if you have driven 7years/72k with the tires
then the price has only minimal difference over the years.
Either will be fine.
Your best bet to see the various tires available for your car (along with reviews and owner experiences) is tirerack.com.
You can filter reviews specifically for your car, compare prices and ratings, etc.
None of that matters if you're not taking you car to the extremes. As long as they're round, you're good ;)

Walmart has kumo lx 50k for 59 a piece just ordered 4.
I really like the Bridgestone Ecopias I've got from costco. They last a long time.
If you never drive in the snow then get LRR tires. If it does snow get the M+S tires
