In answer to the original question, no.
I have rims now and they work fine. I have no pressing need or desire to switch to discs.
I have no argument against discs. I have zero experience with them, but by most accounts they seem to work well and people seem to like them. Nobody would buy them if that wasn't true.
If I stay with rim brakes it will be because they are simpler and less expensive to maintain. I like cheap and easy. :-)
