I only started reading fic more recently and in several cases I like second person fic, but character/reader seemed like a warning sign of badfic before I even read one.

I search AO3 by kudos usually, because sorting by hits or comments favors multi-chaptered fic. I just checked for Hockey RPF and oddly that seems to be more the case for comments than hits, not sure why. I have a friend who prefers sorting by bookmarks than kudos. I'd be interested in seeing what the differences are, across several fandoms, but I'm too lazy to check.
