Tremolo or hardtail?

I’m considering a second guitar and thinking of going for a hardtail. I have a squire with a tremolo currently, but never use it because it goes out of tune, and honestly in a few years of playing haven’t come across anything I’ve tried to play that requires it. I haven’t seen one used in a single tutorial video.

If you aren’t playing Van Halen, do they ever really get much use?

I would buy a decent Floyd Rose, but don’t know if the tuning would be a hassle. Or if I went hardtail would I regret it later?

Other than some rock, where are these really used?
