Yeah, they are some quite popular, Enjin should be rated better maybe and i think they'll progress, such as i don't have doubt at first in Engn and their distribution cause in the end it's all about the audience and your own customers.
Enjin is going to have its time, but i do feel like $ENGN is going to glow with $ENJIN due to their blockchain implementing system for regular games. I can see big companies taking full advantage of it in the future for sure!
