Hmm...
I voted no as well, same reason as the others: the 3940 (US 3286) with it's 17th/18th century bow, stern and canon-deck is slightly bigger, more realistic, and looks just better. Hopefully that one's new sistership 5135 will be evenly usefull (depending on the cannondeck-system-issue).
Concerning the 3550/3750, I loved it a lot as a kid, but like bonniebeth I have a problem with the design of the captain's cabin and bridge (actually the complete stern); it doesn't fit with the design used for the rest of the ship. The bow looks like from a 19th century ship while the stern looks like from a 15th or early 16th century vessel.
My 3750's & Co are destined for use as "Spanish conquisdatores' ships in a 16th century diorama.
If they would re-release it with an altered bow-design (somewhat similar looking to the bow of the 4860 Ghost Pirate ship), it would be even more looking right as a "early galleon" (late 15th-early 16th C.)...
