That is a kinda of vague question. We do not know your Toon's Specialization nor do we know your "play style".

I hear lots of disagrrements in the Forums regarding the Dreadnought. Some say it is a disappointment, others swear by it. I do not own one so cannot speak to that ship, either way.

I do own the Tactical Oddy and the Tactical Vesta. I love both ships equally, but I cannot fly them the same way in combat for obvious reason. They have strengths and weakness each.
I honestly am on my Escort Carrier "kick" right now.
