My favourites are probably Naughty Dog and Guerrilla at the moment. Sucker Punch and Japan Studio after them. A few notes otherwise, the SotC remake was developed by Bluepoint Games, not Japan Studio, and LittleBigPlanet 3 was made by Sumo Digital.
Game information was taken from Wikipedia and limited to studies belonging to Sony. I didn't want to mix too much, because many games were made in cooperation with other studios. But for these two games I made footnotes.
I have no idea what OP wants, but nope Sony and MS studio aren't similar at all, not in critical reception, sales or type of games nor frequency of releases. Their only similarity is being owned by first platform holder.
I recently created a thread about Ms:
Sony has 14 own studios, Ms 15. Both companies, according to sources, even employ a similar number of employees ~ 2600+. So there are similarities :)
It is known that Sony has a more stable team, and Ms has done a lot of shopping in the last few years, but we will only see what comes out of it.
You're missing some games off the list...
I know. I wanted the list to be specific, so it contains only recently released games and only the most important ones.
I tried to limit myself to PS4, but some studios release games so rarely (e.g. Polyphony) that I didn't want to limit myself to just one title (to give a bigger picture).
