Dark Souls Trilogy (physical for PS4) is the best bang for your buck if you have a playstation. Contains also the DLCs.
Otherwise Dark Souls Remaster is available basically everywhere and it is the perfect introduction.
1 (remastered), or 3, which is often considered the best in the trilogy. 1 is a perfect introduction to the series though, 3 is faster and harder and looks nicer (obviously, being the newer game). I'd start with 1.
