It really all does depend on your preference. The Panasonic has some features like GPS, a slightly longer zoom, a larger grip, a Leica lens (Although not as good quality as a Leica rangefinder lens!) and some more advantages. The Canon also has a certain appeal, I've always liked Canons, and I don't know much about Panasonics, but I'm sure that they're good cameras.
The Panasonic has a SLIGHTLY larger sensor (Larger by 0.03 inches larger) although not enough to make a difference. It also has a higher res screen, and I like the top design better, but that's personal. I like the pop-up flash on the Canon, but that's also personal. The Panasonic looks better on paper, but it also costs about $70 more.
NOTE: don't be fooled by megapixels, more megapixels doesn't mean a better image, just a larger file. Anything over 5 is sufficient.
So, go to a camera store and try them both out, see which you like better.
I hope that I helped!
