Tough to say, but just based on their business practices, I'd say Warner Bros. Interactive Entertainment. They publish great games (both Arkham games, the newest Mortal Kombat, the upcoming Injustice: Gods Among Us, and others), but how they treat companies working under them as well is why they are my favorite.
One example of this is with their purchase of Netherrealm Studios (made up of the team that made Mortal Kombat before Midway Games went under). According to Ed Boon himself, about two weeks into development, executives sat down to meet with him, saying that they understood he was used to a one-game-a-year schedule being enforced on him. However, they wanted him to take however long it took to make the game good. The result? Mortal Kombat reboot, one of the best received Mortal Kombat games ever, and easily the best received of the 3D games. And the development of "Injustice: Gods Among Us" has proven that those weren't just empty words.
I mean, after the newest Mortal Kombat game, the hardest work for a fighting game (the engine) is already developed. It would be easy to slam out a quick story in 6 months, reskin the characters and moves in 3 months, and tweak the graphics in 2 months, then send the game out after less than a year in development. Instead, it will be almost exactly 2 years between the release of Mortal Kombat and the release of Injustice: Gods Among Us. Why? Netherrealm Studios spent almost a year tweaking the online system because of the complaints from players of Mortal Kombat. Considering Netherrealm Studios is owned entirely by WB Interactive, the publisher could have easily bumped up the developmental schedule to force the team to move on to the "meat" of the game. Instead, they showed great trust in allowing the developers to work.
In short, if EA makes promises, then doesn't deliver, WB Interactive does both, all without being too confident. Hell, just on the new Mortal Kombat game, they sold 3.7 million copies across all platforms, more than any other Mortal Kombat game. Arkham Asylum? Just under 7 million copies. Arkham City? 8.4 million copies sold. All of those don't include the digital game sales. And yet, despite those great sales, Warner Bros. has only opened up one new studio, and even then only for mobile and tablet games.
TL;DR, Warner Bros. Interactive, for showing business sense, and being a great publisher for developers.
