I prefer steel on my MTB's, and Ti on road, however I don't mind either however. I have a steel gravel and roadie right now, and they both ride wonderfully, however my Lynskey R230 was the best riding road bike I have ridden (compared to a Tarmac Elite and Tarmac SL3).
On mtb, I have ridden both, and prefer the feel of the steel MTB's I have (Niner SIR currently) to the Ti Lynskey's, a Seven a friend has, multiple Niner EMD's, and a couple carbon bikes. It just feels the best, and I am a little less nervous about trail damage, although anything can break...
