Naughty Dog, Santa Monica, From Software, Bioware, CD project, Rockstar and ... no that is pretty much it.

Naughty Dog and Rockstar, are about it for me.

Of course I trust in Nintendo, few companies match their level of polishing and it's easy to tell when a game from them will be good or not (at least for me), plus they own most of the IPs I'm interested in. Other than them I can't really think about anyone else, I've never played a ND game so I can't count them, same goes for Platinum since sometime they come up with pretty bad games...

Bethesda, CDPR, and Remedy. That's about it.

I trust Nintendo and Level 5. I really don't have a bad trust relationship with them. I mostly trust the developers who talk more about making a game than how well it'll sell or how much money they're making off it. That, to me, takes out the genuine care for game developing. Notice Nintendo and Level 5 rarely talk about how much money their games make, only occasionally releasing sales figures for PR use. To keep it short, I trust Japanese developers over western ones because of course there's a financial side to every business, it is the core of every business. But if a company can be more open about the product they're making, they approach game development much differently. Atari to NES is a prime example in terms of software. Where Atari was focused on putting out crap just to meet a deadline and make "guaranteed money", Nintendo just made fun games. The success came out of their passion.

Everyone do some mistake one time or another.Having said that, the one I trust most that i remember by head now are:

Nintendo(in general)
Naughty Dog
Square-Enix
Spike-Chunsoft
Atlus

I'm sorry but that's really wrong.  Nintendo of the NES era was one of the most cut-throat businesses in video-game history and a lot of their success came from that.  For example, they were able to carve out a near monopoly in North America by forcing third parties to sign exclusive contracts, a clause which was eventually determined to be illegal in the US.  Many of their moves were without a doubt anti-consumer.

I still think he's been a great contributor to the industry overall. He just seemed to get stuck at a certain point and unable to move on. Kind of like George Lucas, who had the potential to become one of the greatest movie directors/producers ever, but he had to get obsessed with Star Wars and never managed to move past that, Indiana Jones and American Graffiti aside.

That wasn't because of his work or contributions to the industry, it was because he often lies and misleads the gaming public and press, which makes it very hard to trust anything he says.  He would probably be a lot more respected if he'd just keep his mouth shut before his games release.
