Canon SX40 or Nikon P510?

The advantages of the Nikon over the Canon are - slightly smaller and lighter, HDR, better resolution and slightly better sharpness, better zoom, and the advantages of the Canon over the Nikon are - better low light behaviour, slightly faster, better battery. Am I right? Did I miss something? So which camera is better overall? I would appreciate opinions from people who tried or used both cameras. Thanks.
