Whenever possible, if a better rate comes along, I consider cancelling the reservation to be a last-resort option. I always try to modify the existing reservation first. If I must cancel, I save my cancellation e-mails so I can compare reservation numbers with the contract at pick-up to make sure they got the right one.
