Ti would lighter.....and stronger......depending on the alloys.....and about 10 times harder to work with.....SS is used mostly for corrosion protection,or in the case of bike frames....to give you something to rub on.....

I wouldn't own a stainless frame myself,not that there is anything wrong with them,looks like crap when it's dirty......you could give me a Ti frame and I wouldn't throw it away....but I wouldn't buy one just for riding around.Overkill.

I can't even think of a reason to buy one.....keep up with the Jones' I guess.Well maybe if I was going to ride around on a ships deck while at sea for a couple years......
