Since you put it like that i would say sony.. It might seem like they get a lot of praises but that is just from its fans which is a lot on the internet.
From the other camps people dont seem to think sony accomplished anything except selling a lot of ps2,s for no real reason.
Nintendo would be the obvious choice but they get recognition in some shape from everyone. Nobody straight up hates nintendo even if they are in the other camps. They get the appreciation they deserve as they always have. I will also say though that i dont agree with people saying they saved gaming. That would be like saying suddenly all phone makers started making shit phones and people stopped buying them. Untill one day motorola came along and made a good phone again. The phone sold well and suddenly companies knew once again that they have to make good phones if it needs to sell. So motorola saved phones. Nintendo just did what others would have inevitably done.
As for microsoft i feel like they have done more harm to the industry than help it.. The only thing they can boast is making online games streamlined for consoles.. They didnt invent online games. Pc had that for many years beforehand. Heck they didnt even invent online on consoles. The ps2 had that (good example of how people forget whatever sony has done) what they have done is move the industry into overpriced map packs, pay for online and basic consumer rights violation. The only thing they have ever done to differentiate themselves in a disputably non evil thing is the kinect. And even that is just a new version of the ps2,s eyetoy (theres another for ya)
