I think every type of slide mechanism can have problems if the owner does not maintain the system correctly.
Personally I like my hydraulic slides. Never had a leak, they open and close smoothly and are quiet. I have read lots of horror stories about electric slides. Mainly the issue seems to stem from undersized electric motors. Cable systems I can see having a lot of down the road issues. Cables jumping off a wheel, motor failures, stretching cables are only a few examples. For a good idea of how they will work ling term look at most any garage door.
