Ti is, accurately IMO, often described as 'soft' riding and able to absorb/damp road bumps and vibrations. Round tube shapes do not offer the stiffness required for racing...again, just my opinion. Hydroformed or mechanically formed tube shapes 'may' offer such, but the ones I have ridden (Litespeed) are not all that stiff.
On crappy roads, Ti can really be smooth as silk. Again, a lot depends upon the frame design (angles, lengths, shapes, etc.). It's damned durable stuff, easy to take care of and I'm told it you can ride the same Ti frame for decades if you don't fold it up in a crash.
What is your body size, weight and what type of riding (touring, sport, club, racing, climbing, etc.) will you be doing?
I have a Litespeed that I rertired after one season...not stiff enough to suit me. I spent 33 years on steel, one on Ti and the last 7 on carbon. I still ride my steel frames every now and again. You know the drill with steel...lively, good road feedback and a choice of many alloys, buttings, lugged/welded construction, good repairability, easy to build it as stiff as a brick or touring ride soft, etc.
There are riders here with far more time on Ti than me...Moots and Lynsky IIRC. They will have some good info for you.
