Obviously there have been leaps and bounds with chassis development, handling and ride. But it doesn't mean the newest may be your most favorite. For me it was Arctic Cat's F chassis, we still own one an F8. What I like about it above the rest I have owned is the rider position, felt like a wider stouter chassis as to how it felt when you sat on it, and I also felt it the easiest to throw into and aggressive riding pattern, and overall liked how it handled and cornered. My favorite F chassis was my F1000, shook like you wouldn't believe at idle but was like riding a freight train, miss that sled. So what was your favorite chassis amongst the sleds you have owned?
