Price - check e bay for finished auctions for a guide.

Quality / look - About the same quality I would say with small variations. You will probably find that you will need to do some work in post to get the footage to look the same.

I should add that I have never compared these cameras directly but I have used both. Personally I would sum up the differences this way - canon, bright and sharp. Sony, softer and gentler.

I expect with a bit of colour tweaking they wiull be fine side by side.
