Lots of hitch brands out there and I'm currently in a TT so I don't really know the latest and greatest. The last time I towed a 5th was about 7 years ago and I had a Reese manual slide 16K. It is a basic hitch but did the job. I did find that hauling the hitch in/out of the truck bed was a total pain. This, along with the loss of my pickup bed, are what ultimately made me go back to a TT. I'll go back to a 5th again someday when I'm traveling more than working. The simplicity of just backing up and hooking up the TT is nice.
As for actually towing, you're in for a treat. Assuming you have enough payload and truck, you'll find the 5th tows as well or better than the TT (usually better but TT tow-ers with expensive hitches get cranky). The weight of the trailer concentrated directly over the rear axle is much better than the weight resting near the bumper.
Turns are different due to the hinge point but it's really not a huge deal to get use to. You pretty much figure it out after the first couple turns. Just be aware and you'll get the hang of it super quick. Again, you're likely in for a nice surprise.
