Fwiw, one of my teammates in the endurance race is a Losi guy and one of the best non-pro 4x4 drivers in our area IMO and he was matching his SCTE times with it on the first pack. And he was a few tenths off that yesterday with a detuned 3800 setup to run 2.4 hrs. My other teammate also drives a Losi and is only a few tenths slower than this guy, but was running the same laptimes in the sc10 as he does with his SCT-E.
The truck is at least as fast as the competition (and with less power), and more adjustable, for better or worse. Let's face it, if someone is running well in one make, they generally won't try something else, or at least not long enough to realize any potential. There aren't many fast sc10 drivers down here yet for that very reason. And its also the same reason you won't see any serious criticism of the other brands from me.
