4.5" coils - whos is best?

I am looking to upgrade (~3" to ~4.5"). Who has the best riding front coils in the 4-5" range out there? I have seen them available from RE, Rough Country, Rusty's, etc. I have 3" procomps now, and while they have not sagged much, they ride like crap (too stiff). I am looking for a lower rate coil that will give me the height. Help me spend my money!!!! (oh, and if you have some setting around, and can convince me yours are the best, I will buy them from ya).

I would lean towards RE or Rusty's. now this is just my opinion not the gospel...........

Rusty's (vs. RE) seemed to be softer to me. It depends on your rear springs if you want to balance the suspension.

Rubicon Express... unless you want soft, then go with SkyJacker.
