Not the brand but the type
Tempered glass?
Higher quality liquid applicated? (Zagg/tech Armour)
Cheap cling on type (X5 for $2)
Prefer the tempered thin glass but I feel they are so hard to get a perfect installation.
I'm very paranoid about getting dust under the screen so I go CRAZY haha. I apply the protector in the bathroom with the hot shower running to get all dust out of the air, then I also use a can of compressed air to make sure the screen is clean.
Oh I know what you mean. I do the steamy bathroom along with my lint roller and sticky tape. This last time I couldn't get a good install so I'm going protectionless.

I just recently purchased and applied the Spigen Curved Crystal on my I6, and i have to share it's a pain to install. I had to go though the second one that came with it to get it perfect. But the end result, in my opinion, is a good screen protector for the price. I've done many installs on all the iterations of I Phone's since the I3, and this screen protector is the most difficult to get spot on.
