It's kind of a weird question to compare handhelds to their console counterparts.
The original Gameboy was in some ways more capable than the NES and less so in others.
GBA seems somehow more capable than a goddamn n64 for 2D and was never ever made to handle 3D games.
NDS started with a better version of Mario 64 so it anchored the perception of the system at around n64 level for some reasons.
And 3DS started with some fairly high budget games that distort the perception of its power compared to previous systems.
Vita is weird because I'm pretty sure Sony never actually bothered showing the full extent of what the system is truly capable off like Capcom would with the 3DS.
Like seriously if you look up Capcom on 3DS and Wii, you would think the 3DS is running circles around the Wii!
And really this kind of comparison ALWAYS compare the handhelds on the console's terms so stuffs that are clearly pointless for a handheld system are overvalued while other elements that are the whole point of handhelds are ignored.
I really wonder what we could have expected from a n3DS title built around the New 3DS hardware. How much better would it have looked compared to the OG 3DS? I think the n3DS had a bigger improvement than a lot of people realized and it was just never taken advantage of by an exclusice designed ground up for the hardware.
It's kinda like the Gameboy color in some ways, GBC is really way more powerfull than the original Gameboy but hardly any games truly makes that clear. If you look at the Zelda games for GBC for example, there's nothing there outside the color that make you think it would absolutely never run on an original Gameboy.
For example I'm pretty none of these games would run on an OGB even if you disregard the colors.
But that's like 5 games out of how many? And pokemon ain't one of them too so even back then people didn't really care all that much.
