I have tried Kvaesito, Niagara, Nova, Kiss and Lawnchair(and forks), personally I prefer Lawnchair because it it the most standard regarding workflow and has all if not most features one would want in a launcher. Plus the fact it is fully FOSS and supports Arcticons. If you have a small number of apps you typically launch then Kiss or Niagara(Paid Pro version recommended) would work nicely.
