Bloom: 20K Waterproofing, 20K Breathability, cost's more, is a shell, fairly warm, limited pocket options (no breast pocket on the interior of the jacket, this is one of my only critiques.
Saga: The On Deck is 10K Waterproof and 10K Breathability, it cost's less, it's a shell, fairly warm, not sure about the pockets, more color options.
You decide. It really comes down to personal preference, and where you will be skiing. If you are somewhere that has a wet, heavier slushy snow, I'd put my vote down for the Bloom, I love my jacket, got it on Black Friday, at 137.5, so it was basically a steal.
