The list is from my own subjective opinion. It maybe not correct or suit for you.
I move it from "favorite" to "avoid". Its developer continuously associates extreme political remarks with this software. That makes me not able to trust it. How about one day the developer goes crazy and puts virus in it?
It's very buggy (for example, it often "stay on top" while I don't allow it to do that). And after I uninstall it, it leaves crappy information in Windows registry which still associate all media types with it. Deleting its garbage wasted me pretty much time. I'm usually not unhappy with crappy software, but this one is too crappy and I wish I never heard it.
