For the price I do (certainly better than Ranchos ). If the sky's the limit on prices, though, I'm sure there are far better shocks out there.

As far as the Airaid goes, I think the K&N is a bit better because replaces the stock ribbed rubber pipe, which should allow for a bit more airflow. I do realize I'm splitting hairs a bit, as the power difference is no doubt too small to measure, but what the hell - an Xterra needs all the help it can get in the HP department.
