You're asking a member of GrapheneOS to summarise their experiences so obviously you'll get a pretty positive answer.

It works very well and there's the ability to have Google Play in a sandbox should you need apps that require and depend on it or if you are going to use it more like the average person. If you used Android you'll feel close to home. Unfortunately some apps block running on any OS that isn't a Google certified one but this isn't something we can control. I'd recommend checking if your apps work on there first and if it not working is a non-negotiable.
