I started with a stainless rod and then eventually went with the coated rod and glad I did. The reason I did this is because after awhile, you will get reverse rifling marks on your rod. Thats all I needed to see to switch. Like stated above, wiping frequently should take care of the bad side of coated rods(imbedded material in the coating).
Oh yeah, don't worry about the coating coming off, thats not even an issue.
