Im a fan of games in general.
I like a lot of variety, so it turns out i game on Nintendo platforms and PC.

PC has very similar games to what release on Xbox and PS so makes sense to just get that

nintendo.
i started playing on SNES, love SMW, DKC, metroid and zelda.
then mario 64, zelda oot, mm, ww, metrid prime and xenoblade just got my heart.
tons of fun with smash bros, mario kart with friends.
now with wii U, i got back the feeling of SNES with lots of great platform games, tons of fun with smahs and mario kart, and waiting for XCX, new zelda. In other words, Wii U is bringing back all my best gaming feelings i ever had!!
although the service sucks compared to others, the games worth this.

To be honest, I like some things about each company but have much more things I dislike about each company then I like. Of the 3, I prefer Nintendo software so I get Nintendo hardware more regularly but if it was for Nintendo's software I'd go PC for the most part. Imo, all 3 companies make horrid business decisions with Nintendo being the biggest culprit of the 3.

PS is always my primary console. I buy Nintendo's for their exclusives but NEVER buy third party titles.
MS I either borrow a friends for exclusives or just youtube them

I guess I'm an Xbox fan since I play on Xbox consoles the most, but I do like Nintendo games more.

Nintendo, Microsoft, Samsung fanboy here.

I'm a fan of all three of them, but I tend to like Ninty's games/systems more!

Sony is the best all around having good hardware and software.

Nintendo has bad hardware and a few good software titles.

MS has good hardware while having the worst 1st party software.

PS>xbox>>> Nintendo

Thankfully, this gens sales reflect my opinons on consoles. So, BOOOOM!!!!!

My preferences are split something like this:

45% Nintendo
30% PC
25% Sony

But seriously though. Asking to choose one is like trying to choose between tits, ass or punani.
