Which porting studio made the most impressive Switch ports?

[curl-6]

My vote has to go to Rebellion North. Their ports of Sniper Elite 4, Zombie Army 4, and Strange Brigade are astonishingly close to the PS4 versions, with none of the low resolutions, blurry textures, or framerate drop normally seen in boundary-pushing Switch ports. Amazing stuff.

Runner up has to be Saber. The Crysis Remastered Trilogy are among the best looking games on Switch, and stuff like Witcher 3, World War Z, and Kingdom Come have no business running on a 2015 mobile chipset, yet Saber made it happen.
