I would have enjoyed Kara's promotion to Commander of Pegasus, because it would have provided a very rich source of new material for the show. I think she'd earned a change to prove herself in a command position, but I'd probably see her as an XO before a commander. Maybe Lee's XO? If Lee were not in the picture, I think she could have done an admiral job of commanding the Pegasus, but would she want to? I don't understand how much "command" experience she'd had or how long she'd been CAG and if the duration of that experience would warrant that kind of promotion. But I think I am overthinking this and trying to fit military into fiction. I think she could have made hard calls, but I also think she would have taken more risks than Lee or Adama. On two calls, telling Lee to stay behind and nuke the cylon facility in Razor and jumping the Fleet away when the cylons captured NC, I think Kara might have chosen differently. I always thought Lee's decision to order the nuke strike was unnecessary, so I don't care that much about that one. She could have chosen differently without causing too much harm, IMO. The NC situation seems trickier. I guess I'd see that playing out with Adama making the call instead to Bug Out while Kara would have wanted to stay and fight. That could have been a great dramatic moment.

In short, I do think she was capable, but I think things would probably have not run as smoothly as they did under Lee and Adama, mostly because she has a very different leadership style that may or may not promote unrest and disobedience?? Not sure. I do think she'd have been respected more by the Pegasus crew than Lee was.
