Kvaesitso 100℅. With the widgets setup for favorite app pinning, app tag filters for searching (made me not miss Nova launcher app drawer folders) and ability to add third party app widgets is a great mix of Nova, AOSP, and KISS.
I like discreet launcher. So many oss launchers don't support installing web apps from browsers, but it does, and it keeps my home screen clean. Only thing i don't like is that it flows icons as a list, so if you, say, remove an app early on the list, it moves all the apps after it back one.
I haven't used mlauncher and I'm not sure what kind of tweaks you're looking for but I love Niagara launcher. I recently tried a couple others for a pretty extended period of time but installing Niagara again felt like coming home.
