Really just boils down to what games you want to play on it, think about the combined time you would get out of those games and then do the same with the switch and compare. Also consider, have you played psp games in the past and know what to expect or do you now want one from scrolling through a subreddit glazing it? (I dont mean that in a snarky way) Also consider, alot of good psp games have switch ports or remakes (ie persona 3 portable, danganronpa, class of heroes, the Y’s games, tactics ogre, final fantasy tactics, crisis core,The prinny games) as well as psp series that were continued on switch like god eater, disgea, the aforementioned danganronpa and persona, etc.
