1.-PS4
2.-XBO
3.-3ds
4.-Psvita
5.- Wii U

(i own the ps4, wii u, 3ds and ps vita)

The only current-gen console I've picked up is Wii U, so I guess I'd rank the other four based on how interested I am in the games they've got out or on the way.

1. Wii U
2. Vita
3. 3DS
4. XO
5. PS4

1.PS4
2.WiiU
3.Vita
4.3ds
5.XBO

honestly 3ds would probably be 3rd if I actually found the time to use it.

1. Xbox One

2. Wii U

3. PS4

4. Vita

5. 3DS

1. PS4
2. XB1
3. Wii U
4. 3DS
5. PS vita

Currently:

Wii U (I can play multiplats on my PS3 xD)
PS4
XBO
3DS
Vita
Not too fond of handhelds.

By end of next year:
PS4
Wii U
XBO
3DS
Vita

Wii U and XBO might end up switching places depending on what comes out for them both next year.

In order of how much I use them:

1) X1 (bought November 2014)
2) 3ds (bought November 2014)
3) WiiU (don't own but my roommate has one so I play alot)
4) PS4 (bought at launch)
5) PSV (never played)

Though I would probably rank the ps4 last since I regret buying it (because I don't really use it).. but it felt wrong putting it below the PSV which I've never played.

1. PS4
2. PSV
3. Wii U
4. XBO
5. 3DS

PS4
Wii U
XBOne
PSVita
3DS

For me its

1. 3DS
2. WiiU
3. PS4
4. Vita
5. XB1

But if Zelda U is half as good as it looks Wii U will prolly be #1 at the end of it all. Only own 3DS and Wii U but the rest are in the order I plan to get them...if I get them...
