I guess your mileage might vary. If you're keen on a particular app and you can't make it work, that's a frustration. So far I haven't found any reason to come back to a standard OS, and I appreciate my phone not sending constant signals to Apple or Google to the tune of hundreds per day.
Only problem - which I actually think is a feature is that I don't get any notifications for a lot of apps, unless I actually open the app. I really think this is a great thing because most of these apps that use google services for notifications are just sending marketing modifications which I would have blocked anyway. I do sometimes miss WhatsApp call because the notification doesn't work properly but I have told all my friends and family that they can contact me on signal for fastest response.
