Prime 1 is atmospheric as hell, I love it. Really like how all the visors, beams, and upgrades work with the UI and exploration/combat are very rewarding. And it's definitely the best for lore, logbooks/scans are a huge component for me.
There might be objectively better games (Super Metroid I think is absolutely sublime, a super-tight 2D experience that's rewarding to master and I flip-flop on these two as my absolute favorite of the genre) but Prime has a nostalgia boost going for it in my case.
