Depends upon whose bearing it is. The right ceramic bearing should run rings around a steel counterpart; that said, not all ceramic bearings are the same, as some have discovered to their detriment. LN Engineering developed their own bearing system, experimenting with different materials both for the balls and the cages before settling on the design marketed. The resulting product is made exclusively for them, and is not available "off the shelf", regardless of what many seem to think.
And their design works, with over 10,000 installations there have only been a handful of failures, most related to poor installation techniques, retrofitting an engine already full of metal grit from an existing IMS failure, or contamination of the bearing by metal from an unrelated engine component failure.
