hmm...I would say DS for the huge library of games..and the huge amount of good-great games..
the only people who don't like DS games are sony fanboys..and i'm really serious here..the DS has the most casual games..and shovelware..but also great titles like
LoZ:PH, Ninja Gaiden:DS, adnvance Wars: Days of Ruin (it got me into AW...I hated all other AW before it) so yeah..you've got alot on DS
the PSP lacks games really..it's a second choice...you can always put a NES emulator on it... ^_~
