Oh no no, quite the contrary mate.
WiiU is the best system I had to date. And I had literally everything out there apart from american and chinese consoles.
I've been playing WiiU with such joy and pleasure it's crazy.
Mario Kart 8- dear god it's the pinnacle of fun racing games. And split screen 2-3-4 players? Very few games beat that, if any!
SM3DW- Imo it even tops Galaxy. Amazing platformer.
Bayonetta 2-one of the most impressive action hack and slashes
Zelda BOTW-I'm still nowhere near the end but it may be the game I enjoyed the most in my life (and I hate Zeldas!!! I had to force myself throught WW and OOT)
Splatoon-This one took me back to my youth playing Counter strike together with all the rage. What a wonderful team shooter
Smash Bros-Incredibly polished (even though elitists prefer GC one) one of the most incredible party games
DK Tropical Freeze-dear lord this was fine and challenging
Lego City Undercover-My first game on WiiU and...wow. If you ever as much as touched a Lego, you will love it. I'm not a fan of GTAish games but this one was brilliant.
Other gems
Luigi U, Pikmin3, Xenoblades,Wonderful101,Captain Toad,Shovelware knight, quite a few eshop titles, Nes remix...
As for the switch you (currently) have Zelda (already on WiiU), Splatoon 2 (in summer, looks like the same game) and Mario coming maybe in winter ...
Plus manufacturing quality seems to be rather bad with Switch as far as I could see from videos and in person. (I dont have it yet, my mate does however)
