PSP had some fantastic games from LocoRoco, Patapon, SOCOM, Wipeout, Metal Gear Solid, Twisted Metal, Syphon Filter, Resistance, Killzone, Ratchet & Clank alongside Secret Agent Clank, Daxter, 2 major God of War games, and even an exclusive Ace Combat.
Vita on the other you could count on your hand how many major titles it hand. I certainly loved games like Wiepout 2048, Gravity Rush, Uncharted Golden Abyss, and Teraway, but it still wildly pales in comparison to the PSP. Not to mention you HAD to buy the stupidly expensive proprietary storage. So Sony didn’t do the Vita any favors.
But like Nintendo has pulled off, a dedicated handheld with a dedicated library is a thing of the past.
