Is either one superior to the other?
I can't do bootmii the best way as I have the updated code preventing me from using the full brick protection. And I'm not sure if having priiloader on top of it or in place of it is superior in this situation
Without bootmii as boot2, priiloader is the best brick protection you can get. If you can install bootmii as an ios do it, but be SURE to install priiloader.
