Replying to SI&I System vs Salomon Guardian/Atomic Tracker

I am starting my backcountry career this year, and am super stoked! However I need to get some touring equipment. I'm probably only going to be doing small excursions around the Sea to Sky Corridor (2-4 hours) to start off. I am have a pair of 192 Bent Chetlers, and was wondering how the SI&I System compares to Frame touring bindings like the Guardian/Tracker. Ill be using this ski steup for 70% resort, 30% backcountry.
