I would opt for the spacers if you need to increase height, but otherwise like how the car rides and drives.

Coil overs are not really meant as ride adjusting options. You can adjust preload which does incrementally change vehicle height, but there's a very limited range that the coil-over has to be in to work properly. Otherwise you get bad ride quality and handling characteristics.

The quality units available from places like RideTech, Verishock and Viking are actually designed to place the car at or near stock ride height. Any lowering typically comes from changes to the spindle pin height, or a dropped mount lower control arm. This allows a longer shock which provides better ride quality by being able to run a lower rate spring.
