Yes I have both. My 3DS is broken now and My little brother still play Minecraft on Wii U (The Switch version interface is worse tha the Wii U version for him)

Still have both, still love them.

Yes, I still have them, and I still prefer my wiiU over the switch as of now

- Xenoblade chronicles & xenoblades X are both better than xenoblades 2 on the switch

- Mario kart, new Mario + luigi, and many more are basically the same games

- I have 6 Zeldas on my WiiU, only 1 Zelda on the switch

- ZombiU, Pikmin 3 and Wonderful 101 are my 3 favourite Nintendo exclusives from the past 10 years

- Mario odyssey was overrated, you cant even die in that game, everything was far too easy, Mario 3D was not great but I prefer it

- Mario Galaxy, Mario Galaxy 2 is on the wiiU, not on switch

- I can control my TV/projector with the switch controller

If they bring ports of at least Pikmin 3, wonderful 101, Wind waker, Twilight princess and Xenoblades X, Ill sell my WiiU and rebuy everything on switch, until then, my wiiU is an ESSENTIAL CONSOLE, because I really like video games.

On the other hand, my 3ds is basically unused, I don't sell it because I really cant get much money for it. But there is really nothing on it that I would say is worth to keep it. Maybe just Pilot wings, that one is a blast on the 3ds. But I never liked pokemon or animal crossing, just not my things, and the Mario games on it are far too easy for me. Zelda I prefer on the bigger screen for immersion, I can play them all on the wiiU.

Most of my time with the 3ds, maybe half the time, was monster hunter 4, I loved it, but now there's monster hunter for switch and ps4 and so on, so I can do without.

Also I always hated the second joystick on the 3ds, was terrible, and I cant even see the 3d effect on it due to my eyes. I have friends who could see the 3d but they said it was not worth the trouble and gives headaches. 

I actually find the gamepad more comfortable that the switch, it always surprises me when I pick up my wiiU to play and the gamepad just feels comfortable and lighter than what it looks.
The switch on the other hands cramps my fingers maybe because I have large hands and long fingers. To be honest it was worse with 3ds and Vita.

I'm like you I had 3ds but never was a big fan, if anything probably my most overrated console of all time, both the wiiU and dreamcast had better games than 3ds for me. 3DS was popular due to jRPGs but I never got into them, tried a few and they seems repetitive and too basic. Nothing remarkable besides monster hunter 4.

The wiiU on the other hand had very challenging games, I thought Mario U was the best side scroller Mario ever made, I thought zombiU was one of the best experiences of my life with dual screen and no pause on inventory and the real pressure and fear of dying with only 1 life with no way to go back to a checkpoint, then pikmin was my favourite exclusive Nintendo of all time, to say its challenging is an understatement, then wonderful 101 became my favourite Nintendo exclusive of all time, then Bayoneta 1 and 2, Rayman legends was also originally only on wiiU and was amazing, then Xenoblades X becoming my favourite jPRG of all time, then playing monster hunter for the first time in full HD, I  could go on and on.

Rayman Legends is one of the most underrated games ever. Wii U is the best place to play it.  It is a truly great game.  

Only a Wii U.

Still prefer it over the Switch because the U had Xenoblade X and Pikmin 3. It seems this could change at any time, though.

Not enough rpgs for me to grab a Wii U and I preferred the Vita for handheld gaming. Bought a switch because console quality rpgs.

Yes I owned both. And every Nintendo console aside from the virtual boy, so it’s a natural progression that I would purchase a switch. Having said that, I never really got that much into the Wii U...never took to that controller.

I also have both, but yeah I’d say a poll here isn’t that representative...

Anyway, WiiU was Nintendo worst console, there’s some fun things on there but most attempts were forgettable and uninspired. I don’t have a big library for it, and the amount of Switch games I own is already greater. 3DS however is great. Probably ended up being my favorite handheld of all-time, though the GameBoy Color is still up there. There’s plenty of amazing games to be found on 3DS and I thought the hardware was great. I loved the 3D effect, always used it, and thought it was a huge help in especially platforming games because of the added depth perception. So much so that I’ve actually gotten worse at jumping in games on other “regular, 2D screened” systems. I just can’t see where I’m going anymore.

Oh I'm well aware VGC won't be an accurate cross-section of the general population.
