It's all personal preference, because I have a different setup
I use BSE for everything. Believe me, I've tried everything and every combo. For me, i like a backpiece that is one piece. IS and SGP shields have separate stickers for the chrome, which adds seems and there is inevitably overlap which is ugly.
Bodyguardz is OK, but I could never get the front screen part on, without irregularities. Also, I kinda like the tackiness on the screen as well, and I think BSE is similar to IS, in that regard.
My rank order would be:
BSE > IS > SGP > Bodyguardz
im with sgp's and mine does not overlap.
did you install shorter ones first and then longer ones(or visa versa)?
i did short - long - short- long and this method worked perfect for me.
IS, BG, BSE, or SGP
They all must have people who taylor this in duty and they would not sell out the wrong taylored one, which means if someone didn't get it right, that does not mean they produced it wrong.
Those skins are thing and flexible so result can be vary imo.
this is one of the way i find my own satisfaction lol
