I use nova launcher. Idk if it's the best one tbh because I've never needed to try another. It's allowed me to easily replicate my favourite menu I had back on my HTC onem8 for the past several years and move it to new phones whenever I need to without any issues, so I guess I like the high customizability in that sense, and how easy it is to set up and use. You mentioned that the company that acquired it it's a turnoff for you so I guess it's not a very helpful suggestion, but the app itself has very few permissions on my phone and I don't think that any permissions are actually necessary, though don't quote me on that. But it just has files and media allowed and hasn't ever asked me for more. As far as I'm aware the same team and original creator are still the ones working on Nova, and they've said they won't let the launcher start tracking people without permission. They've said users will be able to opt out of any new features, and any data collection involved will be optional. So unless things change drastically in the future I have no reason to stop using the launcher. I know when people hear it was acquired by an analytics company they automatically turn away, but imo analytics are only an issue if they're forced. If I'm allowed to opt out then I'm fine with it. But some people aren't willing to tolerate even that, so I guess it depends on where you stand regarding that.
