I had shutter speed only to 50. I really start to dislike the 24fps.
If you find you prefer the output from other shutter speeds then go for it. The idea of 24p being "cinematic" is a historical thing as much as anything. Films are slowly moving away from it. Sure, some people will claim the hobbit etc looked "fake" because it was shot at 48p, but chances are the projector they watched it on just wasn't up to the job.
