Took another look at it. VA had a problem with the front and some people including me thought it looked too much like a gun. Made the "pistol grip" smaller, increased the engine size and reduced the front.

Opinions 
I actually prefer the bottom one, but I like the forward section of the top one better. Specifically just the double barrel sorta bow sections. I like the curvy part above that for the bottom but I prefer the barrels themselves of the top version. The problem for me with the top one is that the bridge is just a pimple on the ship. It doesn't really look like anything. But it's more prominent on the bottom, the bottom ship is more recognizable in its components. Though maybe that's because the bow section is smaller. Damn who knows. Yeah maybe that's the thing for me, the bottom one is more recognizable in terms of what is the front, what is the back and what is the bridge. The top one doesn't have any focus I think. That's the problem.
