You didn't say how much you were willing to spend, but your two main uses are at opposite ends of the spectrum...you will need a megazoom for the football, which is the easy part. Finding a megazoom that is takes great low light pictures is tough. I don't believe you would be happy with either of the models you mentioned for your intended purposes. I recommend you wait for the release of the Fuji S5200 (next month). It will have a 10X zoom and will have ISO 1600 capability for great low light pictures.
