While I agree that the battleship the OP presented probably tries to do one to many things... the jump drives being the biggest problem... is one thing. If you put jump drives on a ship the ship basically are no longer a major combat ship and should never be compared with one, at least not with the tech levels we are talking about here.
One should be careful saying that this ship would trash that other ship in no time as it is pretty easy to design something to destroy something else. I could probably design a FAC that would destroy both of these ships with no problem with a fraction of the tonnage and cost, but that is not relevant as these ships would serve very different roles in any specific fleet.
