Comes down to personal preferences.
My Dad had slide ins for many years, then when he retired bought a FW since my parents were planning to travel a lot and even snow bird to Florida.
That FW was one huge 32 ft beast with a walk around Queen bed and you could stand up easily in the bedroom over the pin.
I bought a bumper pull since I didn't want to give up my truck bed for gen, bikes, firewood, grill and other stuff that I didn't want to haul in the trailer.
Another thing I didn't like about my Dads FW was the steps it took just to get into it! It had two outside steps and three inside steps for a total of five steps just to get into it! Then the bathroom was also accesses by two steps and then past that was the bedroom which was also accessed by an additional bunch of steps..
My TT, I have only ONE external step up and no internal steps, everything is on one floor level.
Sadly, your F250 diesel is going to be rather short on payload for a FW, most likely nearly 1000 lbs less than a similarly equipped gas version of the same year. That may make finding a FW with a pin weight that will be within your payload when loaded a lot harder.
