Mail.app works fine, but doesn't provide the underlying service and quality Gmail does. It's just a client (which I guess is the current topic). I'd say the Mail.app is better than Gmail because of it's design and UX, but it often freaks out on "large" actions like bulk deletes or moves. Gmail the app only reads what it needs, allows easily selecting many emails (>50 at a time), and filtering. You can obviously search, filter, and do bulk actions in Mail.app too, but I find the versions in Gmail to be way better because they're either faster or more reliable. Mail.app also doesn't totally understand Gmail's tags and that an email appears in multiple folders. I'm always afraid of moving emails around in Mail.app.
