I've owned and pulled various trailers since 1968. Currently I own and regularly pull four trailers. Two have torflex ( "rubber glide" in my way of saying ), and two have leaf springs. All four are tandem axle.
They all tow correctly behind two different trucks, and all ride acceptably. I can't think of one single time that I have been driving down the road and thought to myself, "gee this trailer sure pulls well because of the type of suspension".
To me the real advantage of the trailers I have with the torflex axles is the floor loading height is lower. Which is quite possibly why the trailer designer chose torflex for these trailers.

What he said. The main advantage of the torsion axles is being able to have a lower floor height. Not something we generally need in an RV, but they have their place. I've owned trailers with both. My TT has leaf springs with shocks and rides just as smooth as the torsion axles did. As far as suspension travel there are just too many variables to say one design has more travel than the other.
