After reading that blog entry on the female scorecard of GOT, I'll never be able to look at it the way you do. 
MZB should get a passing mention. Mists of Avalon was a terrific, ground breaking book. Too bad all the follow ups (before and after) plus her other semi-historical/fantasy fiction (Fall of Atlantis etc ) was total crap. The Darkover series, her contribution to the sci-fi world was really hit and miss in the quality of the fiction; mostly hit but again, I'm surprised an editor let some of that stuff through.
Diana Paxson anyone? Again, a little hit or miss.
Now getting off the female track, anyone into world building/alternate history? I think Kim Stanley Robinson is a genius.
For sheer entertainment SM Stirling's Nantucket/Change books are a lot of fun. Some of them are like a train wreck ( so bad you should stay away) but the entertainment values, assuming you set your plausibility meter to "zero" and just go along for the ride, are unparalleled. And he does better women characters than a lot of authors in the field. At times they are all so silly it doesn't matter.
The Change series has been really entertaining as it's set in my little corner of the world, and I have physically been to many of the locations referenced in the books.
