The 2 vehicles serve different purposes so decide what you will do and then get/keep the one that suits. You can't see yourself, so who cares what it looks like? Scooters for in-town errands, motorcycle for commuting and travel. MSF course, YES. It's not only fun, it's a good course.
My largest motorcycle was a 500cc Virago and it had plenty of power. I've had one scooter that got very little use because it felt just one degree above a
Hoveround.
