Scottrade shows execution speed is .74 seconds instead of the industry average of .6 seconds, but their price improvement is substantially better.

Found Thinkorswim. It's quote amazing how albeit 1/2 of the orders for stocks are going to Citigroup, still, with the other 1/2 going to ATD (automated trading desk), how much ATD has made a difference!

EDIT:
It seems though that Citigroup has acquired ATD!

Ok, found the best evidence regarding ATD:
ATD ranks the best in frequency & in amount of price improvement!
