Longevity of aftermarket suspension?

I'm looking at upgrading my current stock suspension with 130k-ish miles, but am worried about the longevity of the major aftermarket companies like King and Icon. I've read all kinds of reviews of people with 5-10k miles and their praises, but haven't really seen much posts of 50k mile or 80k mile reviews. As side from sending them in for rebuild at the determined intervals, how do the aftermarket companies fair in the long run. Any brand stand above the rest? After the rebuild are they pretty much "good as new"?

I'm debating between Icon 2.5 and the King equivalent mainly, but am not opposed to Fox either. I've debated Fox's 2.0 kit that comes in at about $1000, but am worried it isn't as tough, or I'll want to upgrade in the future, so one of those buy once cry once kind of things.

Currently I don't do much off-roading but am looking to increase my outings and there is a chance I might get moved out West for work in the future, so trying to plan for all that. Not really looking to do much more than coils up front and rear shocks. UCA's and everything else can wait until the need arises, if it does.
