I think whether one is satisfied is less about having the best game in franchise (and which are better is mostly opinion in some cases), but more about having a lot of different games and a constant stream of them, and Wii undeniably wins there. I mean Wii had Zelda, Metroid, and Mario all in it's first year with plenty of games inbetween. Wii U still doesn't have Zelda and will never have Metroid, that right there says it all. No real Fire Emblem, Kirby, Paper Mario, Animal Crossing, Mario Strikers, and so ons either while we're at it.

Nintendo Land doesn't even come close to Wii Sports. I played Nintendo Land a total of two sessions with friends, Wii Sports i played for years. Also you forgot Zelda Skyward Sword. And comparing two great Galaxy games to one Mario 3D World game doesn't add up.

The fact is Wii's motion controls were a succes and Wii-U's tablet controller isn't.

The Wii U quality wise ironically probably as many decent third party games even with just a few months of support, Zombi U, Rayman, Call of Duty: BLOPS 2, Batman Arkham, Need for Speed, Tekken, had a decent start, shame it couldn't sustain itself. 

Of course the Wii should have a better overall library, it had 6 years of support vs. 3 1/2 for the Wii U, but the Wii U isn't even that far off.

The main boom for the Wii was overwhelming market success but by and large what that mostly brought Nintendo fans was crappy third party shovelware and "me-too" fitness/dance soccer mom crap-athons.

Wii's Zelda was ripped off from a GameCube game with controls slapped onto it, remove that and Wii's first year is alright but probably a fair sized step down from the GameCube's first year.

To be honest I think I enjoyed my Wii U more than the Wii. While the two Mario Galaxy games are outstanding achievements, beyond that I found Splatoon, Mario Maker, Mario 3D World as my other favorite games as they're on Wii U. Wii U also has the better Mario Kart and Smash Brothers which is not too shabby. And once you get used to Nintendo games in HD, you never want to go back, gimme HD over waggle any day, it never really added much to things like Mario Galaxy or DKC anyway.

Generally speaking though I won't miss the Wii brand (Wii or Wii U) much at all, did not like this era too much, the Wii U fizzling out completely is just the low point. Much prefer the N64/GCN or NES/SNES eras.

I'd still contest that overall Wii had better third party support than Wii U. In its 4th year Wii got Call of Duty, Goldeneye, Sonic Colours, Sonic Racing, Monster Hunter Tri, Sin & Punishment, Tatsunoko vs Capcom, Red Steel 2, Epic Mickey, No More Heroes 2. In Wii U's 4th year it's getting... well, pretty much nothing. Hell, Wii had better third party support in its 5th year than Wii U had in its 2nd.

And while Twilight Princess was cross-gen, it was still released first as a Wii game and provided fans with an awesome new Zelda on launch day. Meanwhile, Wii U will be lucky to get a proper Zelda at all, and even if it does, it'll be arriving after the system's dead and buried.

I have no problem going back to the Wii now, in fact I've played my Wii more than my Wii U this gen. I'm the total opposite, I'll take the Wiimote over HD by a country mile.

Nothing compared to Wii U. Maybe the market isn't that good for Microsoft and Sony these days, but Nintendo on the other hand is struggling...

Microsoft: The original XBox days were bleak.

Sony: The early PS3 days were very much Not Good.

It would be fun to make a list of the top three and bottom three years for all the major console manufacturers.
