They do better on some problems, and worse on others.
Do you have an example of a problem on which CDT or EDT does better than TDT?
I have yet to see a description of TDT which allows me to calculate what TDT does on an arbitrary problem. But I do know that I have seen long lists from Eliezer of problems that TDT does not solve that he thinks it ought to be improved so as to solve.
