I really liked the Arai SignetGT I had a couple of years ago, BUT replacing the shield is a royal pain. I like wearing a dark shield during the day and switching to the clear one at night, which was always "scary" with the Arai. Replaced the Arai with a Scorpion which was surprisingly similar. Presently wearing an HJC. I would give the Arai the edge ONLY when it comes to the liner, which is the softest.
And after reading the comprehensive article about helmets in Motorcyclist magazine a couple of years ago has made a DOT, polycarbonate lid quite acceptable, even desirable.
Here's a link to Motorcyclist article.
