Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-W730 nor Canon PowerShot G9 X Mark II provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon G9 X II's 3.00" LCD screen is slightly larger than Sony W730's 2.7 screen.
