Replying to ON3P Kartel vs Wrenegade

Other than their intended uses and recommended mounting positions and miscellaneous technical specs, what are the huge differences between these ski product lines in terms of performance all-mountain OUTSIDE of the park? Specifically the 98 & 108 versions of each ski versus the same widths of the other product line (e.g. Wrenegade 108 vs Kartel 108, etc.).

It appears that the popularity is heavily weighted towards the Kartels, but is that just because they have park applications? Are the Kartels really that much better? Give me your opinions.
