Nah, I know those are different, but before actually being in a quest with another player, all you can see is their gear and the better the gear, the higher the likelihood of that player having decent skill.

I've been in enough bad and failed runs with people having great gear to know the difference but it's not there is any other way to even hint at someone's skill level if you don't know them.
