This is the classic 'how much house do you want to power' decision. The Westinghouse delivers 2,000 more running watts, a 50A outlet, and remote start; the Champion covers the standard 6-to-10-circuit essentials mission for meaningfully less money. If your transfer switch is 30A, the Champion gives up nothing you can actually use.

Pick the Westinghouse if…

✓You want a 50A hookup carrying most of the panel
✓Central AC or a big well pump is on the backup list
✓Remote start from the back door matters in storms

Pick the Champion if…

✓You're pairing with a 30A transfer switch or interlock
✓Essentials-only backup: furnace, fridge, well, lights
✓You want the lowest price in the serious-backup class
