I still haven't finished Super Metroid, so Metroid Prime.
I also really like Prime 2 which just felt more intimidating from the outset and hence more satisfying in progression. From virtual panic at the start of the game every time you are in the dark, to master of your domain by the end of the game.
Metroid Prime 3 has the best controls but was a little more linear than I might have liked.
Other M was enjoyable but it didn't really need to be a Metroid game.
