There are a few different options, but if you search through the thread there are only a handful of opinions or feedback on them that I could find. I asked as you have but I haven't been able to get much feedback on comparisons, so here's my 2 cents - I went with both of the Sharp offerings...the standard G20B and the newer G30.
The G20Bs are the more expensive of the two, but I did get a good deal online so not too much more. They are not uncomfortable, but are a bit nose heavy. They are bigger, which was better for my Wife with rx glasses. I also like the lens size as I wasn't distracted by seeing the frames. They (for me) had a slight light reflection from the TV in the upper part of the lenses or the frame. I found if I changed the angle by moving the glasses around or the ear pieces up it was better. They, to my eye, had the truest color representation and sharpest picture.
I found the G30s to be lighter and more comfortable, plus they didn't have that upper reflection of the screen light in them. They did however have a brownish/orangeish tint to them, and to my eye the picture appeared less sharp. The lenses are smaller, so you will see the frames a bit as you watch TV (think sunglasses size rather than 3d glasses).
Hope that helps. I don't think you can go wrong either way...had I just gotten the less expensive G30s I probably would have been completely happy with them, but since I got both and did a bunch of side by side comparisons I went with the G20Bs.
