Tough question. There is not any great way to compare programs that I know of. And, many programs excel at specific areas of path not necessarily at all things. But, I will tell you some of the programs I hear the most about.
In no paticular order
Stanford
UCLA
Univ of Washington
Mayo
Univ of Mich
Hopkins
Mass General
Emory
UVA
Cleveland Clinic
But, let me warn you the best program is an individual thing. I wouldn't trade my program for any of these or any other in the country. There is only one reason I can think of to only wanting to go to schools like these and that is if you want to be a big named academic research person. Otherwise any of the mid to large sized university based programs will give you all the opportunities you could ask for in path.
