The only one I don't like is the Galaxy Class. I really like the Enterprise in JJ's movies. But of the ones listed I chose the Ambassador class.
I still think those altverse nacelles look pregnant. But I'll vote for the Constitution refit as my favorite.
Constitution Class refit. I've been in love with that design since the moment I set eyes on it in TMP! Without doubt, the most elegant and beautiful fictional space/starship ever realised on the small/big screen - from any/all properties.

I had to pick the original. It was the first one I ever saw and I fell in love with her immediately. Even though I saw the refit and the D a couple years later and thought they looked nice, the original had already etched its way into my soul...
