John Deere PTO Clutch - OEM or Aftermarket?

I need to replace the clutch on my GT235. It started making a racket and I thought something in the motor let go until I pulled the clutch off and no more noise. Has anyone used an aftermarket clutch? Or should I stick to OEM parts?

I was looking at this one:
