I suppose a useful question to ask might be "What do you intend to photograph?".
Ultra long focal lengths aren't particularly useful in my experience. Unless you're a paparazzi photographer or intending to specialise in taking grainy images of shy wildlife I doubt you'll make much use of lengths greater than 100mm (35mm equivalent).
From a personal point of view, I'd go for the Canon or Panasonic amongst your shortlist. They're lighter and have the ability to take longer exposures... if I had to pick one over the other it would be the Canon for the ability to focus manually.
