I don\'t know how shaky your hands are so it\'s hard for me or anyone to really answer this question with a \"you should get A\" answer.
IS doesn\'t allow \"faster shutter speed\". Rather it allows you to use slower while still have a higher chance of getting a good image. Keep in mind that IS doesn\'t stop motion. So if you have IS and you shoot at a slow shutter speed you can have sharp stationary objects but people in the picture who are moving will become blurry.
Also keep in mind that the focal length also makes a difference. In general the rule of thumb for non-IS shooting is 1/F. So if you are shooting at 24mm you generally need 1/24 shutter speed to get a good image. And for stopping motion the faster the shutter speed the faster the motion that can be frozen. Most people say for general sports you need 1/500 or higher (as far as I can recall).
My own personal preference is wider aperture over IS but I like having both.
