Where do you live? I've gotten to use some of the new Aura from Ben Moore and it's great, but its hard to find right now.
Ben Moore also just moved the whole Regal line to 100% acrylic here, so the Flat Finish seems like its gonna be pretty durable now, like Regal Matte but flatter.
I'm mostly a moore's user though so I can't help on the SW.
