I'll offer my endorsement of Strongbags. Although, I do plan on switching to a B&R bags when my current strongbag carry on falls apart or when they hold a sale.

I found out about Contrail bags by accident and I haven't felt the need to look for anything else. I fly with a 390 now and I have a 360 for GA adventures.
