The DS version sounds shit. I hate touchscreen games like that. Its no so bad if you are playing something basic like a puzzle game, but action orientated games just dont work with touchscreen.
I'd assume the PSP version has those catagories of wrestler due to its limitations over the PS2 version, where they can throw everything into the mix. That said, sometimes simplicity is the best thing all round.
I like the PS3 version, its far and away a huge improvement over the turd that was SD vs Raw 2008, which was the only Smackdown game that I got rid of within a month. I usually get a year of on and off gameplay til the new one comes out, but that one was just god awful control wise.
Of course, the 2010 version is just around the corner, and to be honest, I cant see it being that much different to the 2009 version.
