Smart Doorbell...which?

Hello guys,

i'm looking for a smart doorbell and im currently between the Eufy S220 Smart Doorbell, the Aqara G4, the Reolink and the Unifi G4. Im located in EU.

I will already have Unifi Cameras so thats the only reason im considering the Unifi G4.

What do you think? It seems that in Europe the Eufy is extremely popular whereas the Unifi G4 is not at all.
