A lot depends on the look you are after also. You can pretty easily hide a TBI unit under and air cleaner with ease. A buddy has a 66 Corvette with a 427 and TBI and unless you remove the air cleaner, you can't see it. A port fuel set-up is pretty obvious unless you go with stack injection and can run the wiring under the intake or something.

If you do not care about looks, the port fuel is the way to go. In some cases, you can literally tune each cylinder throughout the whole RPM range. Can't get any better than that.
