The standard circle has few sharps on it, despite that the sharp keys are the most common (at least for fretted string instruments, which tend to predominate in this forum). If you only care about chord roots, that may not be a great hindrance to you. My experience, however, is that the standard circle is just too incomplete, so I use fuller representations that are more flexible--either grids or strips.

P.S. Not a circle, but a series that only "loops" enharmonically (a seldom useful relationship for proper notation). You seldom go across the circle (the most discordant intervals), so there's no real advantage of a circle over just counting forwards and backwards from your relative reference point. Simple, and no enharmonic ambiguities. Most people find it easier to apply pattern/distance relationships in the same orientation than to rotate their frame of reference mentally, so why use a circular representation unnecessarily?
