I've only played REmake 1 and REmake 2, but I enjoy REmake 1 more by far. In fact, it became my favorite game of all time, and the first time in a long ass time where I actually restarted and played through a game again immediately or almost immediately after finishing it.
I think based on what I've seen of the other games, Resident Evil 4 and Resident Evil VII would be my 2nd and 3rd favorites, not sure what order they'd be in. 4 because of Shinji Mikami, VII because it looks to basically be a modern day version of the classic RE formula, which is great. I also am quite excited to get to original RE2 soon.
