this is a bit like flying vs driving. If you're in the drivers seat you have control - you hope - and your destiny is in your own hands, if you're in a plane it is someone else driving (unless you are an airline pilot). The accident rate is lower for planes per mile flown but if it goes wrong then it usually does so in ways that make the headlines. Still, more people die driving than flying.
When the 'cloud' goes down (or at least some part of it) then you'll notice this immediately because of the large number of sites going down all at once. But when you compare it with the accumulated downtime of all those users had they not been 'cloud users' but hosted on their own kit then it is very well possible that the balance is still in favour of hosting in the cloud.
