For sealant wax/glaze i only use Autoglym Radiant Wax Polish
For pure carnuba types i have used P21S (which is ok),
I also tried Pinnacle Souveran (around 80 dollars for the small jar). I used that on a customer's red F40 and i was extremely impressed. I really like this wax especially for black, red, and darker color cars.
Next on my list to try is the Swissvax Coucourse. (about 200 for the jar).
In the end, what brings gloss and depth is proper paint preparation, not the actual wax. Wax is just icing on the cake. Proper polishing + wax > wax alone always.
