From my basic research, the drivetrain has less friction, so you save a couple watts- not a huge deal for me or most of us I would guess. It stays very clean, which has the double benefits of reducing wear and because you don’t get the grime, you keep saving the watts. Once dirt gets in a normal oil, friction goes up making it slower; think valve lapping compound- oily grit being forced onto moving parts.

The hot waxing is slightly better than drip in because the drip in has carriers that evaporate leaving space in the chain rollers. The hot wax fills all the voids. One video I watched said that using the drip and then after it dries doing a second drip helps in filling up more voids.

It seems that a lot of people will hot wax and then every couple hundred miles will use the drip and after a thousand miles will hot wax again.
