Weather Sealing
Unfortunately neither the Canon PowerShot SX420 IS nor Sony Cyber-shot DSC-HX300 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 SX420 IS and Sony HX300's LCD screens have the same diagonal size of 3.00 inches.
On the other hand, Sony HX300 features a
Tilting screen where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels whereas the Canon SX420 IS has a fixed type screen which provides less flexibility in shooting positions compared to HX300.
