I think this depends on the subject. An f/2.8 lens with a 3-stop image stabilizer allows you to shoot at shutter speeds you'd need f/1.0 to achieve on a non-IS lens. Canon doesn't currently make a prime with an aperture larger than f/1.2. As long as the subject is immobile (I don't mean people posing - I mean static exhibits like art and sculpture, architecture, etc., and theOP is going to a museum), you'll be better off with f/2.8 + IS. Certainly, if you are shooting people or anything else with the ability to move, IS will not help and in that case, a large aperture prime is best. (That's one reason the 35mm f/1.4L is on my wish list.)
