My Definitive Version of Sonic 3 & Knuckles
Sonic 3 Angel Island Revisited with mods has an insane amount of customizability and this is by far my favorite way to play the game. Origins wish it had even half of what's even in the base games content and mods just take it even further. I will attempt to list all the mods that are active in this video.

Some of these have probably been either replaced or upgraded by now but I cannot be bothered to re discover and re organize what is and isn't compatible with each other so for now this is what I'm working with.
