1.5 TFLOP for Switch is bogus that's the FP16 number, divide that by two to get a more accurate representation.
For me ... no I don't really care that much *buuuuuuuut* even Breath of the Wild is starting to look a bit dated as we start to see more and more higher end PS4 games.
Also it's probably going to suck being stuck at 720p mostly for another generation because 1080p is hard for XB1 as is, something even below that is going to struggle even moreso.
For Nintendo's cartoony styled games like Mario Kart, Splatoon, and Mario, it should be fine. I don't think Nintendo really even used all the Wii U's power until games like BoTW and Xenoblade X.
It's mainly a portable device, I don't see anyone but the hardcore Nintendo fans using it as their only console, so as a portable it's very powerful. Battery life though ... well you may want to carry an extra battery if you play a lot on the go.
