After having both, I'm sticking with ceramic.
I agree with Webby that I have asked my stove to ingest rain wet wood on several occasions without cracking the ceramic cat.
The steelcat cloggs up a few times a season in my setup. And I believe the faster light off time of the steelcat, while true, is just not very significant since most reloads in winter are done on an already active cat and the ones that aren't, the majority of time spent getting to active is going from red embers to fully engulfed. After that, things heat up proportionaly quicker.
