I loved both games, but I played 'em both on the PC.
ME2 is great (visuals and atmosphere, the characters, too. The story/plot could've been better, IMHO), and there aren't really any mods (so I guess you won't miss out much from the PC version). So if you're going to play one on the PS3, then get this one. (I'd still recommend playing ME1, tho'. I saw the YT vid for the comic thingy for the PS3 that covers the events for ME1 and, IMHO, it wasn't really good)
Dragon Age: Origins has awesome characters/dialogue (Morrigan FTW!), but I wouldn't recommend playing it on anything but a PC because of the mods and some community fixes.

While we're kind of on the topic of bioware, does anyone else feel that the addition of fuel in ME2 was a 100% bad idea? It's like "Go, explore the galaxy! BUT NOT TOO MUCH"
I didn't mind that one.
The heat clip thing, on the other hand, was rather annoying. I still prefer the ME1 heat dissipation mechanic over ME2's limited heat clip mechanic. A hybrid system would've probably been better: once you're out of heat clips, it switches to the ME1 heat dissipation thingy until you can get more heat clips.
