I use Next 3D. It's a rather unique launcher with the visual effects it has.
The downside is there's zero tech support if you have a problem (not even an-auto reply email that they got yours), but the only issue I have is it'll occasionally freeze and I'll have to force close it to get it to respond again. I think it may be abandoned at this point, but it's still on the Play store. It was also $16 when I bought it, which is another downside.
Someone gifted it to me, so I've been using it for years and now I'm spoiled. All other launchers just look bland to me and not much different than OEM launchers.
