I don't commend anyone who remains mute throughout a run. Normally, someone would have to be at least a little friendly to earn my commendation but these days I have learned to be grateful if they so much as say hello. If both say hello, my friend and I split our commendations between them, if I'm alone then I'll decide based on who was more friendly/noteworthy typically. Otherwise, I don't give much attention towards how good a player is. I don't feel this is a game where people can be "impressive" honestly speaking, so I'd much rather encourage those who can at least distinguish themselves from bots.

I'll also commend people who fail a bit/a lot if they are polite and very apologetic about it since I appreciate that in a person and I don't like them to leave totally discouraged. So in short, a person's class as zero impact on my decision.
