Personally I really like the matte protectors, but I had to accept that they do scatter light more, and visibly alter the clarity of the screen. That being said, I recently decided to try a "new material" that a friend told me about, and I have to say it's hands down the best non-matte screen protector I've ever tried (out of maybe a half dozen different varieties).
You can find it on Amazon: http://www.amazon.com/iSmooth-iPad-Screen-Protector-Replacement/dp/B00989QKA8/
I'm not really sure what it is that's different, but somehow the material is a huge cut above the other (admittedly, cheaper) screen protectors I've tried. Once it's on, it truly is invisible and the overall quality is way higher. I wouldn't likely have spent this much on a screen protector (which I realize is a pretty lame reality... $600 device and I want to spend less than $5 to protect the screen?? How backwards is that??) but since a friend recommended it, I'm glad I did. These really are, in my opinion, the best out there. The price also appears to have dropped a bit since I bought mine, and considering the above is a 3-pack... they're about the same price as the inferior ones I've bought before.
They are not matte however, and I've written to the company requesting that they make a matte version. If they could somehow make a matte one out of this same material, I think I'd have my 100% perfect solution, rather than the 95% perfect I have with their clear version.
Hope that helps!
