The ability for us to use our own logo is very important, but also so that we can choose which products are sold in each channel - it allows great control over inventory management as well! We did not have this option before with another platform provider (they were doing an integration project).
I like how easy they make adding new channels/products simple by allowing you just select them under one place rather than having separate accounts set up per product type or account category /etc etc.. It's nice being able find what info i need without using google searches because of all their different tabs within sites & pages where information could be buried somewhere else if searching online only :).
