Is the difference enough to notice or are they all about the same? Is they all leave it about the same I will go with what lubes best.
they all leave the same, the difference is in how the oil keeps the fouling in suspesion.
i use a 50/50 mix of Mobil 1 Synthetic 5w30 and ATF and it makes clean up a breeze, carbon is very easy to remove even after 500rnds
The only one I've personally tried that seemed to not build up a lot of carbon, even in places notorious for building up carbon and should NEVER be lubed ( the gas piston on an M249, it seemed like the ultimate test of claims to "reduce fouling buildup") was Milcom TW25-B. Some great stuff, just a little expensive.
Tetra isn't as bad as most of the other lubes I've used personally either.
I've heard really good things about most of the synthetic engine oils. A guy I know uses it and says it keeps stuff from building up and sticking as bad as the other oils he's used. Since all non racing oil has a pretty high about of detergent and suspension additives it makes sense to me.
I have found Froglube to leave absolutely no junk when it burns off––if you burn it off. Here is a video that I made comparing burn-off of several popular "boutique" lubes against it:
