You mean you wouldn't call the Switch underpowered?
Unless you're running a £5k gaming p.c everything is underpowered, what's your point?
Did anyone compare the power of a gameboy advance to a PlayStation, or a PSP to an Xbox360? Nope. Why? Probably because you couldn't be that stupid and get away with it.
Now ofc gaming sites love to stoke some fanboy fire for hits; some people are just simply to DENSE to think about the logic of comparing a battery powered device with a screen to a huge black dedicated powered, helicopter fan cooled slab of electronics sitting heavily under their tv.
You'd have to be a bit of a moron not to be able to logic your way through why such a comparison is nonsensical at best, and simply trolling at worst.
Hierarchy of home consoles:
PS3<PS4<Xbox X. Xbox X is the most powerful home console.
Hierarchy of handhelds: PSP<3DS<Vita<Switch. Switch is the most powerful handheld console.
So to answer your question, no. I wouldn't call Switch underpowered. It's far better than my previous 3DS or Vita. And it will remain that way untill another 'more powerful' handheld comes out worth caring about. Playing a handful of shitty android games on a shield tablet doesn't for me, like pretty much any gamer out there, rival a true dedicated big name handheld, and Switch is the best one out there right now. Period.
