I've heard Royal Purple is good stuff. My dad swears AGAINST Amsoil ever since he blew an engine in his 510 like 30 years ago lol
High quality oils with the least amount of additives are generally the best. Synthetics are great. Honestly I don't think it matters too much as long as you change it regularly enough and take care of your stuff.
I recommend using cheap/regular diff fluid if you have a clutch type aftermarket LSD and just change it often. The clutches wear and get the oil dirty requiring frequent changes.
