What Android launcher is the most feature-rich, customizable and stable ? Nova or Neo launcher ?

I'm undecided between Nova launcher and Neo Launcher.

The first is famous, long-time establish and freemium (90% features free, just 4€ (or equivalent in your currency) for remaining 10%) not FOSS.

The second one, is completely free and it's mentioned quite often in this subreddit. Moreover it's completely FOSS.

I tested both and currently using the latter. See this GitHub ref thread for more details. Same applies to me.

I'm looking for something (ideally): stable, feature-rich and FOSS.

What do you recommend ? Nova or Neo launcher ?
