Two graduates this year I know used those materials. One guy broke 270, but he is in general ridiculous. My friend got a solid ~240. Not great by SDN standards, but by everyone else's pretty solid.
It also depends alot on how much time you have. I personally want to focus on UWorld and supplement nightly Secrets reading. This would be my second pass of Secrets. Note that I also just had my Medicine and Family Medicine rotations and just did the AAFP questions for my FM shelf as well. So it depends on how much knowledge is fresh as well.
Use whatever you feel comfortable with. I just mentioned my plan, since you were wondering what people are doing. As with everything else on this board, take with a grain of salt.
