The often asked 5er or TT, and pretty much the same responses as everyone wants to make their RV choice valid, even a few motorized RVs were thrown in as they felt left out, don't you love human nature.
Simply put, when properly hitched both types tow fine, and when improperly hitched, both types have their shortcomings. Your best bet is to go to RV shows or dealers and view as many units as possible.
Noticed you have been on this forum for 2 decades, no doubt you have your preferences when RVing. Whatever choice you make have as stout of a truck as possible, most towing issues start there.
We just went through this last year, initially looked at 5ers and TTs since we still have a truck in good condition. After a year or so, we began looking at motorized RVs as well to give every RV class a chance.
When RV shopping we tried our best to leave our preconceived perceptions about RVs at home, we would have never looked at motorized RVs if we didn't. Vigorous research was required as we have always had 5ers and TTs.
Since we were looking for our retirement rig as well, we took our time vetting every scenario to our specific needs. Never had issues towing either TT or 5er, always had great towing comfort, although this time out DW chose class A.
