Neither. I am a little put off with SGP and how they changed their films. The adhesive is too strong now and if you get any dust under it during installation, its nearly impossible to get out. I really like the Switcheasy Pure+, Griffin or Power Support for the crystal shields.
If you are looking for a shield, nothing comes close to Clear Coat. It has not orange peel effect and repels fingerprints fairly well. It does have a bt of a sticky feel to it and it makes it a bit harder to slide your finger over. Check their website for kiosk locations near you in a mall. Its worth the $10 to have one of their professionals install it. They are usually very very good. I am a perfectionist and I had not complaints about their installation.
