Clear or Anti-Glare really depends on where your using your phone the most. If your planning to use your Mogul on the street alot then probably the anti-glare is the best way to go. But if your using it in-door the most then clear's the path.
I've always used Anti-Glare styled Screen protector since I use them alot more outside then indoor.
Forgot to say....You should consider a Case to protect your investment. Seidio slim case seems to be the highly recommended one from different forums. (My order completed processing on Monday so still waiting to receive it right now)
