Roadrunner the power steering on the ultra is silky smooth so is the motor guide xi5 my buddy has 1 of those. The motor guide is more quite while turning and it has a wireless footcontrol. The reason I went ulterra is I launch a lot by myself usually tie rope from boat to the back of the truck. This Jan on a ramp in the middle no were the rope broke needless to say it ain't any fun watching your boat float away now if this ever happens just deploy motor and bring it back with the remote.
