It might be hard for you to judge which ones are "popular" if you haven't spent a bunch of time around here already, but the idea is that you (probably) want to pick a face that doesn't already have like 5 different people using it.

It's not necessarily heart related, just screenshot a few that you like and we'll tell you about them and you can make a decision from there. 

[spoiler]desu the most important thing is picking something that you actually like; uniqueness isn't as important imo[/spoiler]
