I think thinner mustache covers philitrum better. With the full philitrum covered your focused on the mustache size now as the space between the nose and lips. With a thinner mustache the area overall is still same height but your eyes focus to either the thinner mustache or the exposed half of the philitrum.
A stubble is scientifically proven to be more attractive anyway, dont cope. Also we always talk about the halo effect but Cr7 is the most classic example of it, he has a good body but his low inhib, charismatic and arrogance is why he seems that attractive, his face isnt that good and I am a big fan. Imo marchisio, giroud, isco, ramos with a beard, hell even the jap Honda is as good facially. However they are NO bodies to most people ( aka not real into soccer, just follow big clubs/biggest players, and they dont play like ronaldo which is a full of flare, selfish and eyecatching style. Or at his level )
