Get the Z7+

Interface is much smoother. They update the system regularly. An issue I had with the Buzz was vod movies would stretch out to fill the screen. So ultra wide movies would look all stretch out, not on Formuler.

I haven't really used recording as I just use timeshift.

Another feature the z7+ has which you probably don't need is the air cast remote. Basically you can use your phone as a remote but also mirror what you have on your z7+.
