The shake-down on shakes

I just read a story in The Atlanta Journal Constitution about fast-food milkshakes.
In the article, they sampled shakes from a grand total of three restaurants--Krystal, Wendy's and Chick-Fil-A.
The most shocking detail is that the Krystal shakes contain 1,060 and 1,010 calories compared to 520 and 810 at Wendy's and Chick-Fil-A respectively.
Perhaps not by coincidence the Krystal shake was the writer's favorite.
I am a little disappointed that the writer only tried three places. To me, you have to include Sonic, Steak and Shake and Dairy Queen in a story about milkshakes.
Around here (how in the world does Anniston/Oxford/Jax not have a DQ?) I'd put Jack's milkshakes up against anyone. If I have a shake hankerin' I usually hit Sonic, Jack's or Chick-Fil-A, though there are some in the office partial to Arby's shakes.
In my experience, Krystal, Burger King and Rally's shakes leave much to be desired.
Any other favorites at chains or local places?
