I just went from a TT to a 5th.
Pros for the 5'er: lots more storage, high ceilings, easier to hitch only because you can see the hitch, auto leveling is a must,
Cons for 5'er: beware of height issues and tree limbs,hitch is in the bed, must use a pick up. More clearance issues to consider, bed height can be an issue.
Fivers are more expensive. Built in genset are available
In the end a fiver is a bit more convenient. It is fully self contained. Truck storage is not as critical. 5'er is a bit easier to deal with overall.
