I've got JOM coils, and they are very comfortable.
What happens a lot is that once you lower it a bit, you'll kinda get addicted, and want to go lower.
Coilovers are good because they give you that choice, whereas you'd have to take the springs off, and get new ones to put on if you wanted to go lower.
And then you've got spare springs laying around, which you can obviously sell, but more effort again.
I vote coilovers.
