Ghost Armor sent me a replacement after contacting customer service.  I now have the GA on the front with the 3G black slider.  I did love the anti glare, but I must admit, there is a (small) sacrifice to screen clarity.  Just my opinion.
Still love the slider. The white one I had ordered arrived and is going right back. The black matte on my white phone looks and feels great.
Like others said, there's a huge personal preference factor. I'm way too tough on my stuff to just use GA only. I need the protection against banging the corners etc, not just the scratch protection. GA screen protector plus black matte slider = hopefully the last solution. I feel like I ruined enough of the other films by not leaving well enough alone. The GA screen protector is not going anywhere unless I peel it off. Very pleased with my solution and GA's cust service.
