I personally know the vast majority of the material in both roadmaps, so I know that 't Hooft's is far harder to learn from. Anybody can check this for themselves. There's plenty of broken links, extremely rough drafts of lecture notes, and wild fluctuations in sophistication. The ordering puts graduate-level stuff before its sophomore-level prerequisites.

My statement would only be controversial if you believed that arbitrary adversity in learning was necessary to be a good physicist -- and for my own sake I hope that isn't the case!
