Comparable to any other high end factory precision rifle. Just depends on what features you are looking for.
Though my understanding is that the AI's quick change barrel system is more user friendly then Cadex's.
AI definitely has the easiest system I would say, a single 4mm hex bolt and barrels hand screw on and off. The Desert Tech is also super easy but more bolts and few more steps. I almost bought a Kraken but the barrel change process and associated extra tools make me go AI instead. Hard to beat the quick-lock system.
