Plenty...
Paging, 4GB of Memory Address Space, and the list goes on and on.
Now that AMD has forced the issue with Intel, 16-bit is really old school.
64-bit is the way to go, but I am kinda partial
Really though, 16-bit is really outdated. The only real good use of it is to make bios calls (int 10h for example), but you can do that in virtual 8086 mode too.
Protected Mode is a least what you want to shoot for, if not Long Mode (64-bit)
