Depends on what you mean by "tow better".
TT height and profile will be an insignificant factor. The longer & taller a TT is however, the more of a factor it will be in high gusting side winds tho. BTDT once and it was NOT fun.
If you plan to do long trips and want to minimize sway, have good handling and "tow better", things you can do include: get a good WDH and make sure it's all set up correctly, use LT tires on the TV and inflate them to or near max psi, install shocks on the TT, install HD shocks on the TV, install Dexter equalizers on the TT, if the TT doesn't have them upgrade to wider LRD tires (from LRC), run the TT tires at max. sidewall psi. A longer wheelbase TV helps too.
We've done all the above and tow a tall 29' TT that has the u/s of frame 24" off the ground. I love our Reese DC WDH and it's proactive self-centering action. Have towed thousands of miles in 7 western states - no sway on freeways and narrow twisty mountain roads at posted max speed (to max 65 mph) are never a problem, even with a sheer dropoff on one side. Handles almost like a sports car (maybe an exaggeration lol) and is way fun. :)
Most importantly when shopping around, pay close attention to what actual weights will be for both TW & GVW compared to payload cap. of TV. Different brands and models of TT can vary quite a bit for same length, and same thing for CCC. Never go by factory dry wts. - safest thing to do is look at the GVWR ratings and allow 12-13% for TW (a few TTs are up near 15%). Also carefully consider added payload of passengers, pets, groceries, camping gear & misc. "stuff" and maybe a cap. A trip to a scale before you buy a TT might be a good idea to know what your available payload cap. really is. You don't want to end up overloaded and tow poorly.
