While I'm not sure how it compares to others in terms of which is best, mŷ regime is:
Meg's gold shampoo wash and rinse
CG lube and Meg's clay, then dry.
Optional machine with menzerna polish/finisher and a medium foam or soft waffle pad.
CG Jetseal 109 always after machining.
CG black polish, though the R222 will be what I'm trying next after I've used it up.
Wheels bilberry, then dry, then jetseal.
Here is my car right now. No photoshopping but the pic is through a patio door so a shade darker than in the flesh...
