In everyday nonpicky use, the affordable Pana and Canon P&Ss (less than $200 and preferably less than $150) are roughly equivalent-- if you had to buy them sight unseen you'd be able to get good photos from both. They're just not that different. They both take AA cells and SD cards. One will have a slightly wider-angle lens. The other will weigh less or be more compact.
Once pickiness enters the picture, things change. If you take a lot of time exposures longer than 8 seconds, go Canon. If you've seen one too many purple halos around bright objects and can't stand to see another one, go Panasonic. If you like shooting indoor video clips of your cat, go Canon. If you value sharpness over smoothness, go Panasonic, and so on.
