Weather Sealing
Unfortunately neither the Canon PowerShot ELPH 150 IS (IXUS 155) nor Sony Cyber-shot DSC-H200 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
Sony H200's 3.00" LCD screen is slightly larger than Canon ELPH 150 IS's 2.7 screen.
