i love jocks aaaaalllllmost as much as i love thongs. and I even have a couple strappy undies that are basically both.
i dont neccessarily pick the jock by the brand but by the cut. its up to you if you find narrow or wide waistbands appealing, but I go for ones that are softer. i like narrower straps usually, and i prefer pouches that are rounder and have center seams. I dont like being squished. i dont particularly like jock briefs because im so specific about the cut.
some of my favorites have been Timoteo, Andrew Christian, and N2N as far as brands go, but you really have to brows the styles to find one you like. Occasionally there are great sales but a good jock will cost the same as a good thong. I say, try a couple out! light breathable fabrics, non confining/supportive/sculpted pouches, and colors you like
diesel, 2xist, papi jocks have great patterns and are okay but can feel loose on the sides of the pouches or are kinda flat or squishing.
if you're lucky enough to live in a city with some mens underwear stores [gay stores have better options honestly] then i'd look there first in person, maybe try one on
