OEM launchers often include annoying anti-features, like a screen you can't remove and that has the brand's voice assistant. They also tend to be slow, bad at search, and have all kinds of unnecessary phone-home functionality like sharing your location with their owners (austensibly to show the weather forecast).

Besides, I have a work phone and a private phone - different brands, same launcher.

I have lawnchair now (from Nova), I use it to remove the search bar, add more buttons to the dock, and a custom icon pack (though I think that'll work on stock launcher).

I assume I switched to using it since Google changed something I found annoying?
