Obviosly just get a WiiU :P  Im just kidding, but get the one you want.  

Pros

Xbox One has this game I want
Ps4 has this game i want
WiiU has this game I want

Cons

XBox One has this I dont Like
PS4 has this I dont like
WiiU has this I don't like

Final Decision

Gaming is a subjective experience with millions of different opinions world wide.  It would be nice to let people have and make their own decision without people trying to say one or the other is better.  There is actual pros and cons for each console of course but when it comes down to it, people's preferences are different and all three companies offer different experiences.  Just let people enjoy their decisions regardless of what your opinion is.  That is all VGC.  Now try and have a good day :)

Oh and my opinion is to get them all by the way xD

I plan to get them all eventually as well, but one, the WiiU, certainly is a better buy right now IMO.

I´ve already decided, got a WiiU and will wait until price cuts to get the others.

Now now, if anyone is planning on buying one... I´d recommend to stick a little longer with the current gen and wait a few months

Pros:

Xbox One  has Killer Instinct

Ps4 has Vita connectivity

Wii U has my facorite gamess and touch streen inventory

Pc has last gen games in next gen graffics, plus next gen games

Cons:

Xbox One charges for online, is not a graphical leap, doesnn't use kinect effectively

Ps4 charges for online, isn't a graphical leap, Vita remote play is unsteady

Wii U has the worst name ever,  isn't a graphical leap, doesn't have immature games

Pc is large fro my living room, isn't a graphical leap, small ssd so limited game installs

Final Decision

I hope everone enjoys their new Xbox's and Playstations. Maybe someday I will too.  I am a proud owner of a Wii U and PC combonation.  There's no incentive for me to guy a new console.  I love the tablet controller.  I love steam sales.  My 360 controller works wonderful on my pc in my living room.  I will miss not haveing Killer Instinct but atleast I have MAME for the Arcade orinials.  I hope ppl buy Wii U but if not that's there loss not mine.

Already have a Wii U, and unless I get some of the other two for christmas I'll be waiting for a price cut and some games I want on the next gen consoles before I buy them. Although I might end up doing what I did last gen and just not buy anythig that's not Nintendo, I usually always have enough games to play anyways.

Ok, you convinced me! I will get them all

Now that's a quality comparison! now let me give it a try!

Ohh and good thread OP with a good message, just a shame that it will be used in a bad way by people not reading the OP and just trying to sell their console of choice to others.

To the above: Please take your fanboy wars elsewhere.

======

The X-Box One is worth getting so you can hear that Killer Instinct's announcer's amazing voice.

The PS4 is worth getting to stream videos of yourself undressing your wife.

And the Wii U is worth getting to draw stuff on Miiverse.

All well worth their respective prices.
