They can ALL play Crysis.
Crysis 2 was released this week and brought with it a player-driven first-person-shooting experience.
Unlike the first game, however, this sequel is on the consoles too. For those of you with a beefy enough PC, the choice is simple – go for the PC version. Playing a first-person-shooter is always better if you have the mouse option (though the couch comfort and big screen for consoles is nice too).
If you're unsure about the capabilities of your PC, then perhaps you'll have to settle for a console version. So far, judging from the multiplayer beta, the consoles have kept up really well – at least according to these comparison videos.
From all three different versions, it appears that the geometry is nearly identical. The main differences are in texture quality and lighting. Of course, multiplayer maps are tuned for speed rather than the "wow" effect, so stay tuned for a comparison of the campaign.
