Until now I had only had very thin sheet protectors that stick to your fingers by static electricity which attract all the dust as possible, creating bubbles at the surface of the screen. After trying tempered glass I can assure that there is no comparison to make. Small towels for cleaning the screen used to properly remove fingerprints and tempered glass adapts a wink on the screen without any bubbles. No loss of touch sensitivity of the screen to me. A little more expensive than plastic but leaves a real good protection against scratches and shocks.
