I just finished the six part review of the DFRPG set. The final post, which gives an overall evaluation of the game, is posted
here.
There are a lot of strengths to this set, and I think it will be a great introduction to GURPS. It makes the new player experience substantially better, and offers moderate improvements to the new GM experience.
It still has room to improve in terms of production value: art, organization, and layout. There are also some areas where SJG can improve its execution, such as advice for balancing combat.
I have a number of ideas for follow-up posts on how SJ Games can improve on this set for future iterations, and I hope to have time to work on those in the next few weeks.
