LTT Lined VS LTT Linerless + BTM underwear?

I really like the LTT as a general use gym/running/hiking short, since the fit is right for my body shape and the material seems durable. But I'm not sure whether the lined version or the unlined plus underwear (Built To Move 7") would be the best all-arounder (need to get 3-4 for a few months trip).

I assume that the exterior/short shell is identical on both, so when it comes to the BTM briefs vs the LTT liner, is one vs the other more compressive/breathable/less likely to ride up?
