I'm quite inclined towards the Canon SX20IS cos of its Stitch function which the Lumix does not have. I'm quite addicted to stitching photos when i'm out and about and seeing sights.
I tried the Sony HX1 the other day and their paranoma function is really good! just press and pan! But that will only work for certain instances like lanscapes taken in the day. For low light paranoma will be more difficult.

Cameralabs have been known to be biased to Canon stuff in the past. There was a review a while back on one of the Canon models when they did a comparison on movie mode, but took videos in different environments giving the Canon false impression of having better audio/video quality.
