I've traditionally been a PC and Nintendo gamer, but I seldomly game on my PC anymore as it's not connected to my awesome TV set, and I really dislike the direction Nintendo took with the WiiU (although I do own one, it's mostly to play Wii games on since my Wii died).
My favorite console at the moment is the 360, but I have little sympathy for Microsoft as a company. Sony makes good consoles and good games, but I absolutely despise their controllers and interfaces, so much that I just really don't feel comfortable with their consoles (I couldn't adjust to the PS3 at all).
So basically I hate everything.
