Yeah I think CMJ performs pretty well from what I've seen, but still suffers from the limitation that you've got to know your sample count up front.

Okay, I have some more sample test images.  Here is (14,15) at 64, 256, and 65536 samples, respectively:

[IMG #2 Image]
[IMG #3 Image]
And here is (24,25):

[IMG #5 Image]
[IMG #6 Image]
So, both of them perform reasonably well across a wide range a sampling rates, it seems.  Though neither are great at 64.
However, I also checked some other dimension combinations, and found that (14,24) performs poorly:
[IMG #7 Image]
[IMG #8 Image]
[IMG #9 Image]
So it has its problems, too.  But even so, I find the lower dimensions to be better distributed with Faure-permuted Halton than with Sobol.  Though, admittedly, I haven't done a super thorough investigation. [SMILEY ;-)]
