Honestly I just don't really care to anymore. I used to flash custom ROMs on all my phones because I could only afford cheap (100-200€) phones that were filled with bloatware, but ever since I started being able to afford a decent mid-range phone (Pixel 6a was the first one I didn't reflash) I just found out I wasn't actually missing anything, and I definitely enjoy things like contactless payments, and not having something randomly break every time I update.
