Is total face as effective as full face?

I've been using the total face Fitlife for about two weeks so my nose can heal up from my ffm mirage quatro. I really like it. It redirects the air away from your eyes. the only issue I have, is side sleeping with it. where the top straps connect to the mask, they stick out a bit so the second I roll onto my side the strap holder hits the pillow and breaks the seal of the mask. Other wise I have had good luck and my nose is loving it!
