I'm not to sure about the millitary stuff but I do know that the two companies compliment each other very well.....Like for the 350 Titanic all sets from both sides are more than what you need! I can only assume that goes for all Thomas and Gold medal in this case as well.
I say get both if it were not for the $ thing :(
Mr. Perry of Gold Medal Models lives near me and I have seen his 1/350 Titanic and other ships in person abd WOW! this guy knows SHIPS!
Straighten up and fly right.....
