Advice on Suspension Choice

I'm looking to upgrade my current lift and am considering Icons front and rear. They're substantially more than say Toytec coilovers, but from what I've researched they're far superior. The question I have is for the money that will need to be spent for rebuilding($150 per shock) when the time comes, and downtime to do so, is the performance and ride quality worth the hit?
On my previous Tacoma, and '08, I had OME coils, Billys all around, and new UCAs. It was a fairly stiff ride.
My current truck is a 2013 Double Cab short bed, with the poor mans lift(spacers up front and blocks in the rear. Dying to ditch this setup and I only did it because I didn't have the funds to do the lift the way I wanted at the time.

Anyway, any feedback is much appreciated.
