Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon IXUS 165 is significantly lighter (65g ) than the Sony QX30 which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon IXUS 165 nor Sony Cyber-shot DSC-QX30 provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

Canon IXUS 165's 2.70" LCD screen is slightly larger than Sony QX30's screen.
