The first is from dvandom in his weekly roundup, amusingly titled "What comics Diamond would deign to sell me, August 19, 2009," in which the issue is "Mildly recommended," and also wins "The Cardinal Rule Of What If? Stories: Things Usually Turn Out Worse No Matter How Well They Start" Award.
The second is by "zombox" on iFanboy, who gave the story a 4 and the art a 3 (I assume out of 5).
Money quote: "this plot felt more like the Farscape arcs I enjoyed the most when the show was still live. If you were a fan of the show, you should look into picking up this book."
