The Canon has a longer lens and XLR's if that helps you any.
 I have the FX-1 and I would not leave it for a Canon xh-a1 because they are too close to each other. However because you are ready thinking about the Canon just get the Canon.
OR
You can always move on up to the Sony EX!!! Those may be the new drool machines for the next few years with about a $1000 price drop...
