I prefer the XL. Dont get me wrong the X is a beast but the XL takes a lot more punishment and can handle more rugged terrain due to its longer/wider wheelbase. In my opinion. I own both X ss(w/5.9K) and XL(w/picco P3 .28) plus a Revo(looks and on-road demon). My XL is only for off-road use(basher) and my X is on-off road use. Depend what you want. Looks, performance, on/off road use, or just personal prefrence. I couln't decide my self so i have a different use for each vehicle.
