I just got the Legion and I really like it. I had a clear Gpel case on, the Pure Max, I think was the name, and while I liked seeing my orchid gray Note through that clear back, it was a pain. I had a lot of trouble getting the Spen in and out, and the volume rocker didn't work well, and the Bixby button was hard to keep pressing. The Legion feels better in the hand, too. It's little more weight, but not enough to bug me, and I think it's better protected. It went on fine with Gpel tempered glass screen protector but I am ambivalent about that because there are several places that the sensitivity of the screen is definitely lessened. But I'm leaving it on for now.
Good case though!
