I don't think it's disrespectful at all that they transferred all the games into one for the SNEs. Yes, they DID change things, but it's more than nothing. I have SMBDX for the GBC, and SMB2 and 3 for the GBA, so I know them all pretty well. I voted for SMB2, because I like the underground music, the clouds, shy guys, and the whole idea that they're in a dream world was very... DREAMY... ah, dream, relax, sleeping.... plus it had Luigi, Toad and Peach. It wasn't until SMW that they had Yoshi, but at least they had the others for this one. Of course, it's my favorite when I have all of them. If I had to choose one, and would NEVER be able to play the other ones, I might choose SMB3, because it's basically SMB1 to the MAX!, and it has the more... classic enemies than SMB2. If all this time you meant SMB:LL this whole time, then I'd pick SMB3 because SMB:LL is more like a continuation of SMB1 than a sequel.
