I think you will find any of the single stage urethanes that have decent solids contents in them will work fine. I've used ppg, shermans-Williams, valspar, all good. It's there cheap brands that I have occasional issue with, not covering well.
Clearcoat is a little over rated. My friend who is a classic car restorer convinced me to paint my mustang black single stage rather than clear-base. It came out amazing with great depth.
(I colorsand and buff as well. I would use base-clear for multiple colors and metallics)
