The problem with some TI cups is that they do not tolerate repeated high heat cycles and will warp after awhile which is troublesome for the TI cups that have a fitted lid.

I use a SS cup that has provided years of usefulness and will probably last for the rest of my hiking days. I am not a weight weenie when it comes to gear so I don't worry about the pros and cons of TI vs SS weights.
