Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Sony QX30 is significantly lighter (76g ) than the Canon SX710 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Sony Cyber-shot DSC-QX30 nor Canon PowerShot SX710 HS 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 SX710 HS's 3.00" LCD screen is slightly larger than Sony QX30's screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
