What about Ultegra [Di2], 105,

I've heard that the regular cyclist isn't

From 105 and up it is hard to tell the difference when clean. I think I can tell the difference between 105 and DA especially shifting in front and braking. But is it worth the price difference? I don't know but Shimano have to realize that they make their profit because the regular cyclist buys DA components and I think it's a shame that they don't offer the proper gearing for the regular cyclist in DA quality.
