Weather Sealing
Unfortunately neither the Canon PowerShot G5 X Mark II nor Canon PowerShot ELPH 170 IS (IXUS 170) 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 G5 X MII's 3.00" LCD screen is slightly larger than Canon 170 IS's 2.7 screen.
In addition to the size advantage, Canon G5 X MII LCD screen also has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. On the other hand, Canon 170 IS has a fixed type screen which provides less flexibility in shooting positions compared to G5 X MII.
