The battery ones aren’t bad. I have 5 total cameras. 2 are wired ( Spotlight Cam and Stick up Gen 2 ). Then 3 battery (2 Doorbell and Spotlight Cam ). I don’t have any problems with the battery connection wise. It’s just performance wise the electric is a little better. Also any activated motion lasts for a minute instead of 30 seconds. I’d say realistically where you live I only get about 1-2 months before I need to swap and replace the batteries. Weather, amount of motion and all of that causes that. I also have a pretty expensive WiFi setup and 500 meg connection, that’s also very important because I’d say 95% of people with connection issues are their own WiFi causing the problem.
