I actually prefer Season 1.
I prefer season 1, but I still love season 2.
I prefer Season 1 for it's story, but Season 2 had better gameplay.
I love season 2 for its characters and their developments, while season 1 had better talk choices in my opinion (jerk route mainly).
Id go with season 2 because I find it has better replay value.
Season 2 for sure. Season 1's character backstory and choices didn't particularly matter in the end.
I choose Season 3.
