I've had poly LCA bushings in my Duster for about 8 years and 15,000 miles. I've also had adjustable strut rods for about 6 years and 10,000 miles. They're just as reliable as rubber, more so if you lubricate them once in a while. It's unfortunately a controversial subject because some guys have had bad experiences with them due to incorrect installation or other issues causing them to fail, then they form very strong opinions about them and tell everyone else their car will fall apart if they don't use factory-type rubber bushings.
For what it's worth I've also taken my Duster to several track day/autocross events and I beat the hell out of it on a regular basis. No issues with suspension parts failing or alignment changing over time, aside from some cheap shock absorbers blowing out once in a while.
