Which would be the best deal? The quick-n-dirty answer would be the cheaper of the two.
Is one just a copy of the other? Yes and no. I would think they are similar because they are the same basic type antenna, a 5/8 wave ground plane. Lots of ways they can be the same thing and be different, no idea in this particular comparison.
Another terrible way to make a comparison is which one weighs the most? I would assume that would mean it's a little heavier-duty than the other one (yeah, I know, big stretch there).
Something else to think about is that mess of wires going to your house. If the 'groundplane' is above those wires, then they shouldn't make much difference. Key work there is 'much', which opens up a whole 'nuther can of worms, sort of. Shouldn't make any more difference with an A99 or Imax though.
So, which to get? Beats me, you gotta decide that.
