I have two pairs of these as well as the non-rechargeable ones.
Both types do the 3D bit in exactly the same way (as they're supposed to), so the only way to judge them is on comfort and value. In this regard they win over the standard pair. I'm not sure they're worth the extra money on that alone, but if you factor in the cost of the batteries that you won't have to buy over the months and years, perhaps they work out cheaper (or better value, at least).
One unexpected thing that I noticed is that the cheaper ones may be a little lighter and the lack of all round frame made me think there was more lens size. I don't think it matters, even if it's true.
The reason for the one star deducted is the cost and the daft power button/light arrangement.
