I think post #10 sums up my thoughts on this pretty well. It's actually not easy to screw up a Shimano brake bleed (or Tektro, TRP), IME. Those brands have many things in common in their hydraulic brake designs, with the key thing being that they use mineral oil brake fluid. IMO.
I'll add that I think SRAM's biggest flaw with hydraulic brakes is that they bought Avid before they had ever produced a hydraulic brake under the SRAM name. Avid's reputation with hydraulics was/is horrible,and is well earned. And yet, SRAM's hydraulics are just a continuation in too many ways of the Avid hydraulics and their design. They're better, but not "better enough." IMO.
