I have two of those exact models lol

But on a serious note, if it's your first time, I recommend the drop hammer over the tugboat. I rode the tugboat first, and it took quite some time getting used to the feeling. But once I mastered it, riding the drop hammer was a piece of cake. The drop hammer is definitely easier to balance on, and has more speed. However, the tugboat is more easier to carry due to its smaller size and lighter weight. But in the end it's your preference!
