Your crown prince of jiggle physics, definitely not mine.
No particular order or genre. Gribabos (previously known as Gurobase but changed because people thought they did gore), Kreamu, previously mentioned Yeero, Xordel, Nottanj, FPSBlyck, Rekin3D (More Furry/Monster based), KisX (their take on Laura has increasingly gotten worse but their work is still high quality), ZMSFM (Mixed bag of Kink Content), Megaera, Fugtrup (Mixed bag of content), Pewposterous, when you mention Pewposterous you by nature have to mention LazyProcrasinator, and NoName55 (Mixed bag of content).
NylNyl and Bandoned produce content I dislike, but at such a high quality I can't help but not keep tabs on them.
Some up-and-comers and returners are ThreeDust (TwoDust), InitialA, and MidnightSFM.
If you want a glance of peak old content ahead of their time/information unknown, Ellowas and Gnomfist deserve these spots.
Hopefully, the list helps. Maybe some of you would disagree; I don't care.
