It all comes down to what you like - there is no need to upgrade to a VA Ship if you don't want to. The VA ships are realy just there so you can fly your favourite Captain Ship with some extra bells and whistles. I still fly around in my Star Cruiser from RA becuase I love the Nomad skin.
Also, as I recal the VA ships were release a fair bit after cap was increased to VA1? (Correct me if I am wrong).
what class are you? the Excelsior Refit
would be a better choice than the gal x. you can save alot of time traveling or getting to your friends. its a fun ship to play around with. i bought the gal x and regret it.
I've flown all the admiral cruisers, and each one is fun to fly, with their own quirks to get working. Boh versions of the Galaxy Refits have their bonuses, (although it is fun to nap turn onto a raptors fallen shield facing and using the PSL to knock em out of the fight), the Fleet Escort works very well with an Engineer Captain at the helm, just treat it as a more squishy and quick little cruiser
