This. It's all incremental to me. No I can't be 100% free of big tech and surveillance, etc etc - but how much of my data has Google not gotten since I started paying for private email 5 years ago or so?
(Not much cause everyone else refuses to leave Gmail behind 😂 but all I can do is keep moving myself in that direction.)
It's pretty dummy friendly. Accept that some things may not work or will work differently (Most notably tap to pay is a no go AFAIK,) and be willing to learn if something comes up would probably be how I describe it. The only problem that might turn up that an app that you need doesn't pass gOS' security checks, but there's an app level setting to lessen security restrictions if it's something you NEED.
Otherwise, meh? Flashing back to stock is super easy via a google web tool if you don't like it. (I had to for a trip, Ticketmaster was being wonky and all my shows were ticketmaster haha. I've never had a problem before with the Ticketmaster app so IDK if it's an ongoing thing or not)
I look forward to watching the federal govt give 5mil to newly formed X Research to determine if Christianity should be taught in school as the one true religion.
I actually got it to run reasonably on a mini PC in a docker container, but my setup also lets me use CPU power as a psuedo GPU.
