Obviously the PSP would be better. It allows loading from the memory stick and is a much faster machine. I know of no way to easily use external data on the DS.
I've heard that you can execute software on the PSP, but I have no idea if it will really be possible. I hope so, though. Having emus on that thing would rock!
I can't wait till the scene begins to grow on the PSP side. The day Super Metroid is playable at a decent framerate on PSP, PSP will officially be the best handheld ever
