Thanks for the pic lcz128
There doesn't seem to be a difference between the two in terms of height; Generations Scourge just looks bigger because of his 'shoulder pads'.
I don't understand the hatred for Titaniums. I actually thought they were pretty good - especially Ultra Magnus and Scourge. In fact, I probably still prefer Titanium Scourge over the Generations version as he has an accurate alternate mode when compared to his cartoon self.
