Sony PSP vs Nintendo DS

i personaly like psp coz its almost equal to ps2 as supreme lord said and also the upcoming games in psp like metal gear:acid (wat if snkp will make KOF:MI in psp). hmmm i think the problem in psp is that it could have loading times since it is in UMD disk format. that could probably waste our gaming exp.
games in DS are kinda for kids thats y i recommend it for youngsters.
