While I'm still catching up on the modern incarnation (I just hit the post-season of the 2019 season, second one on discovery), you've also got the ones that are a sort of evolution of full-body spinners. In particular, Son Of Whyachi pretty consistently sends opponents flying or rips them apart without the stability/reliability issues of a Gigabyte or Shrederator. Bloodsport has also done some pretty solid damage with a smaller form-factor than Gigabyte during the 2019 season. They tend to be extremely chaotic fights.

I think my favorite example of the problems with class full-body spinners was in 2018 when an opponent managed to rip Gigabyte's outer shell off in one piece.
