The fact that the 270 rocks! For hunting deer sized game the 270 really is hard to beat. I don't reload currently, but could start back (I stopped because I slowed my hobby shooting) The 270 is just the path of least resistance.
Yeah, I know the cool factor is very low, but there is no rifle search. I can get any brand or configuration I want. Yeah, I really love the BC advantage the 6.5mm offers, but for hunting at most reasonable ranges it doesn't mean much. Yeah, I like the accuracy most 6.5's offer, but the 270 is plenty accurate for hunting.
Lastly, I'm pretty sure if I was to get a 6.5mm it would be the 6.5X284. I also think that this was the one to commercialize here. The 6.5 has its following and deserves it, but for most applications the 270 wins the contest between the two.
Whew, I feel better!
