It's probably not so much about traction as it about independent suspension. These things may distribute weight better and can shift the load bearing with minor balance adjustments. Also, consider portability. Individual legs can be folded and stowed telescopically as well as hinged. Trac mechanisms may be heavier and more prone to failure, or at the least, present unknown engineering challenges. Also, losing a trac might doom the mission. Losing a wheel may only impair it.
Btw, I'm not a rocket scientist, just your average engineer. And I have stayed in aHI Express.
