little bit higher velocity, tiny bit flatter trajectory, lighter recoil, wayyyy less muzzle flash, considerably quieter, etc.
and the biggest advantage of them all- with the gas port father away from the chamber the pressures and temps in the gas system are lower = you will likely never break a bolt. Rifle gas has slower, smoother cycling than 16" or SBR stuff, and it has more reliable extraction because the case has had more time to shrink before extraction. And a properly gassed 20" barrel with A2 or A5 buffer system will reliably run basically any .223 or 5.56 ammo that exists.
Think about it- if you dont already have a rifle in your AR arsenal Id highly recommend it. The last 2 ARs Ive built have been 20" Rifle, and I love it. Kinda hooked, in fact. Granted I dont shoot people in the face indoors for a living- I dont even notice the extra length- my primary application is hunting and range use.
I suggest you start with a 20" or 18" Faxon rifle gassed "gunner" barrel, and add a Vltor A5 lower, and build from there.
