I own both but I barely use my DS although there are great games for it.
Castlevania, Mario Kart, New Super Mario Bros. Zelda, FF3.. etc. Also some games work great with the stylus, not to mention it has a better battery life than the PSP and Nintendo products have always held up better than Sony stuff. Add on to that it cost less than the PSP.
As for the PSP, pretty much recently great games have been coming out. FFT, Disgae, Jeanne D'Arc, Castlevania. More good games coming out soon, but I would say the best thing about it is wide range of capablities it has.
Custom Firmware allows for a ton of customization, pretty much like a desktop computer in addition to being able to play PSX games on it (I'm playing my "patch" version of FFT on it right now. PSP also plays music and vids although depending on what else you own you might not use it for that.
I personally use my PSP more but both are good choices and you really can't go wrong either way.
