Ross has his name on quite a few of the "less than inspiring" category. I think this is primarily due to the fact that he spread his name too thin and slapped his label on courses that he barely (it at all) visited. We can set aside whether or not this was a respectable thing to do, but if you look at just the courses that Ross devoted his time to, it's a pretty impressive portfolio.
CBM said himself that he only worked (at all) on a very small number of courses: NGLA, Shinnecock, Lido, Chicago, Yale, St. Louis (tell me if I'm missing any). This is an impressive list as well, but it's a lot easier to get it right when you work on so few courses. Additionally, 2 of these courses don't exist any more, Chicago has been dramatically changed as I understand it (by Raynor and others?), and at Yale he served in primarily an advisory role. That leaves only NGLA and SLCC as surviving CBM designs (once again, please correct any mistakes here).
If you held up Ross' courses (only the ones he devoted his time to) to CBM or Raynor, I think DR takes the cake.
