Bigger is Better if: You Can afford it, You are not Intimidated by it, It will fit in your mode of transportation, It can land and take off on your local runway, you don't have to call the FAA for clearance, you don't knock your friends down with the wing when you turn around while holding the wing, you have a big enough set of wrenches for the prop hub, you can see it at 2,000 feet, you can still get it in and out of your house, You can sit in the cockpit....LMAO! I could go on and on.
