Yep. "neck beards" are really gross!
But back to the OP's questions: my suggestion confirms to my rules. If you don't want to start out a full beard from Day 1 I think you should do it right by growing a goatee right, and then once you have an established goatee then expand it into a beard.
if you don't like the quantity of hair hair involved with a beard then minimize the quantity by growing a proper goatee, mustache, or sideburns instead of growing a beard wrong by ripping it to stubble.
It amazes me how many people get it wrong and shave too high, always looks odd, glad to see I'm not the only one lol
