I would not call it amazing. I had tons of fun with it, mostly a Spelunky machine for me.
The biggest weakness was that 1st parties never got on board long term (I understand why after the sales results). The launch was great but it never found a dedicated audience. Moreover, unlike the Wii U, Sony did a hard pivot as an indie machine. So we never got a ND game for it. And they were not even interested! At least with the Wii U, we got Nintendo's premier teams on it for a good 4 years.
And recently, my memory card died, losing tons of hours P4G. I later heard that those are notoriously unreliable and cheap (quality not price!). Which sucks since they are expensive and propriety. I'll need to check out the modding options for SD cards.
So it has a mixed legacy for me. Great hardware, so so software support, and a terrible memory card solution.
I honestly don't see how any can prefer it to the Switch. The Switch has big boy third parties (Bethsada, CD Projekt, SNK, Square Enix). It's not perfect obviously. Missing EA and others. But then you add Nintendo's first-party and a very healthy indie scene. It has 4 shoulder buttons, bigger screens, and so on.
The Switch (yes, even the OG big one) is my favorite handheld system by far. It's hard going back to the Vita after getting used to those big Switch screens.
Vitas do feel a bit more solid. They had proper BT support! And much better online. So the Switch is far from perfect.
