It probably requires more frequent power drops and doesn't stay connected in floor running situations very well without using track clips.
All I've ever personally had is tube and Super O, and I can't recall a single time that the tube came apart while running on the floor (Christmas, etc) unless the rails are misshapen for some reason. The big thing is to ensure the rails themselves are not bent out of shape or widened at the openings so that the pins remain locked tight. If one twists to get them apart thats where issues begin.But, they can be put back into shape with some pliers.
