When I was a kid we had a 5th wheel trailer and it was always a lot of fun to use. It wasn't large (either 22 or 24 feet, I can't remember) but more than enough space for 4 people.
Personally I think Jayco makes the best one on the market.
Depends on what you plan to do with it...
Tow it once and a while close to home...
Park it on a lot...
Tow it cross country...
How many will you need to put up in comfort?
What kind of tow vehicle you have or will buy...
I currently have a 92 cobra sierra 35 ft travel trailer...
Sleeps 9 in comfort...11 in a pinch...
I have it on a lot within an hour of home, so I dont have to tow it...
I may be trailer trash...but only on the weekends....heh heh
Besides...my lot is lake front on an all sports lake chain...a lot cheaper then a million dollar cottage...
I have quite a few friends who tow actively....get back with some specifics and I'll pass along any suggestions..

Since the tongue weight rests directly on top of its drive wheels, rather than on the back bumper, there is less stress on the towing vehicle's frame. You should have better front-wheel traction with a 5th wheel because the weight of a bumper-mounted trailer can cause the front of your vehicle to raise up.
Drawback---you lose most of the cargo capacity in the bed of your truck. Even when you're not towing, there's this big hitch in the middle of your truck bed.
A guy I work with has a 5th-wheel trailer. He loves it. He's had a 30-foot full trailer, a 34-foot motor home and now the 5th-wheel, and he much prefers the 5th-wheel.
He bought one of those large tool boxes that install in the pickup bed against the cab for extra storage, and he removes the 5th-wheel hitch from the truck when he isn't towing, so that he has the full use of the truck bed.
He says that towing stability and ease of backing are definite advantages. Of course, he doesn't drive the truck when he doesn't have to. The 454 cu engine is just to expensive to drive the 90 mile round trip to work.
If I were in the market, I go for a bumper hitch type. I spent lots of years with my grandparent rockhounding. It wasn't unusual to need to tote a 1000 lbs of cargo home. A fifth wheel makes that difficult or impossible.
As for the balance, the trailer axles can always be shifted fore or aft slightly, 1 or 2 inches, to adjust the tounge weight, keeping the fronts wheels firmly planted.
