IMO there isn't a single format that screams "exceptional PS." I would also caution seeking advice from a random person unfamiliar with reading PSs. In general, these are the things that I think that make a great personal statement:
-Well-written (mature syntax, varied sentence structure, diction isn't forced, tone sounds natural, etc.)
-Addresses the issue of why you want to become a physician; some anecdotes might be fine here, but don't overdo it - this is a professional essay, not a dramatic story
-Your reasons for entering medicine should be "backed up" with "evidence;" rather than simply saying that you like serving the community, for example, you should point to examples of you serving the community and why you enjoyed those experiences; this will make your arguments more legitimate to those reading your application
-Safe is better; more than likely you won't be able to write a truly outstanding PS - be conservative and simply aim to have a solid PS. Unless you've had some truly unique and outstanding experiences, your PS probably isn't going to be the critical piece of your application that gets you rejected vs. invited to interview/accepted
Every individual is going to approach the PS differently - this is just my opinion, and I'm sure plenty will disagree. I really want to emphasize the importance of making the PS your own, though; there really isn't a template that results in an excellent statement that you can simply follow and fill in with your own experiences.
