Honestly I've got all 3 variants of the Bortasqu' and loaded up all the consoles onto the tactical variant. I fly it with my Engineer and it's very different than the Peqhqu. The Bortasqu' is very much a tank and meant for taking a huge beating, although having all the consoles equipped make it a little more versatile. The Peqhqu is nice, but it's still a glass cannon to boot. It may be a little tougher than your average BoP, but it's still breakable.
To each his own I imagine, but I've also got 3 max level Klingons so I have the option of flying both the Bortasqu' and the Peghqu by just switching toons. Personally I love them both.
I think you get a little more bang with the consoles on the Bortasqu' but that's probably because it's split into 3 consoles instead of just 1. That could just be me though.
