Which porting studio made the most impressive Switch ports?

[curl-6]

Yeah Panic Button did some great ports, but I feel like Saber's were more ambitious.

PB seem to have moved on, their last Switch port was Apex Legends in 2021, while Saber's still at it, having released a port of Biomutant just in the time since I posted this thread.

I wonder if Shiver could become a contender in the future; so far they've done three major Switch ports, the excellent Mortal Kombat 11, the rough Mortal Kombat 1 (it's better now than at launch, but still rough) and the wildly ambitious Hogwarts Legacy which took a big hit visually but as a PS5 title is a miracle in that it runs at all.
