Proper linear loading has no gaps compared with coils and Q is better 
controlled.
I had very narrow BW with a 2 element yagi on 160m using coils while it 
was much easier to obtain a pattern with linear loading.
Lost power is better dissipated along meters of straight wire or tubing 
than on wound coils in a concentrated space. 
An high dipole that gets extra gain by ground reflections (at some 
elevations) in an efficient transmitting antenna, but without a pattern 
that enhance S/N while receiving is generally a much poorer machine if 
compared with a directional array.
