IO540,
Being vectored is much easier?
Errm...
Vectors = not sure of track miles (sometimes a hazy estimate from ATC), V/S to have a shot at a CDA, variable quality of intercept angle with LLZ and not sure if we'll be put on the G/S from below or have to intercept from above...
Procedure = LNAV + VNAV, a CDA for sure, and just the right place onto the ILS.
There's a time and place for both, of course, but at regional airports when coming in from the opposite side to the approach direction, the procedure has considerable merit.
...and it sounds to me as though, despite his later protestations, the OP doesn't really know what an approach plate is for, or how to use it...
