That particular Roo was my trailer of choice when we were in the market. Then I compared what I could get the Roo for vs the trailer I got instead, and I went with the TT. The 23IKSS is still a great floorplan though.
To answer the original question, I think they will tow similarly - too close to call. My trailer is over 30 ft long and I am totally accustomed to it now having moved up from a hybrid that was about 19' total. If the OP gets something (TT) larger, it just takes some time to get accustomed to it.
