Went in with realistic expectations so I suppose I could go with:
PS4 - A
Xbox One - B
Wii U - A
I think they are all good consoles that will give us some great games during this generation, but its a slow start like it almost always is. I really enjoy the design of the PS4, small, quiet, efficient UI for the most part, but they will probably need to add some folder type options to the library very soon. I also really love the DS4, I think its a great controller, been using it since before launch on any PS3 games that would support it via USB. I have spent the majority of my time pretty evenly split between PC and PS4 since getting it. Tons of AC4, Killzone, Knack (not tons, just beat it once, and did enjoy it), InFamous SS, and now I can't get enough of TLoU: Remastered. I also have enjoyed the indie games for it, there is always stuff for me to do when I find the time.
For the Xbox, I'm not the biggest fan of the controller, the sticks done feel right, and neither do the bumpers, but its still serviceable. But it won't be taking over my wireless 360 for PC gaming I know that. Well, maybe when I need to use a dpad, but PS4 is working well for that. I have Forza, Dead Rising 3, Killer Instinct, Peggle 2, and some other freebies, but really I have only beat Dead Rising 3. I had a stint of Killer Instinct fever (played the hell out of it when I was younger) but fighting games just don't hold my interest much anymore. Everyone in the house has had a hell of a time with the voice commands. Its in the family room, its just me, the wife, and our roommate so its a quiet house, but I swear "Xbox On" works maybe 20% of the time, after 3-4 attempts I usually just grab the controller and turn it on. Other voice commands it is also pretty terrible at, it will hear me, but perform the wrong function, it loves to "Snap" when I'm trying to do other stuff like go home. "Xbox Turn Off" seems to work well though. I think the design of the box is ugly, but it is quiet which is nice, I really just don't play a lot of stuff on it, I played some of the TitanFall Beta, but the game didn't grab me, while I got Ghosts for the PS4, I'm just not a twitch shooter anymore, Battlefield all the way (which I double dipped, PC and PS4, love it so much).
Wii U, picked it up on the $200 refurb deal, at first we played a ton, and it finally got my wife to play games which I thought was awesome. She is actually the reason we got the Xbox one, she wanted it for the fitness, which she never uses, and after getting the Wii U she immediately said we should have gotten it over the Xbox one in the first place. I haven't owned a Nintendo system since the N64 so its been great playing Nintendo stuff again. I still think its horrible that their online "profile" stuff is so archiac. I should have an account that comes with me to new systems and keeps my library in tact, but I don't trust anything I buy digital on it I will get to use on new systems. Outside of our binge on Super Mario 3D world, I haven't played a ton of other games even though I went out and picked up a crap ton. Mostly its because I have wwaaaaaayyyyy too much stuff to play, and just not enough time. And at the end of the day my PC and PS4 are in my den, while the xbox one and wii u are in the shared living space of the family room so I just don't play either one as much.
