I took both for step/level 1 and 2.
Step 1 - FA for USMLE, UW, COMBANK, Kaplan Qbank, DIT, Goljan, pass program videos, Guyton and Hall physiology, Clinical Micro made ridiculously simple. I had myself spread too thin over the resources, but I managed to do above average ~550 on COMLEX and I passed but barely on USMLE. I should have just done more questions for the USMLE. USMLE Rx is a good source too. More questions is key though and is by far the best advice. However, I'm of the camp that studying for the USMLE + Savarese =/= studying for COMLEX. You still need to add in and fully complete at least one COMLEX qbank because of the ridiculousness of the exam and because of the lack of information you get in the stem vs. USMLE.
Step 2 - Mild studying throughout 3rd year and for shelfs, DIT step 2, Step up to Step 2, COMQUEST, UW 2. COMQUEST was a better qbank than COMBANK, but they don't offer a step 1 version. Again, I wish I would have done more questions. And I really needed more time. I wasn't completely finished studying when I took COMLEX and I had some unexpected call weekends leading up to the test. Plus my PE was 3 days before and my ride bailed 1.5 days before so I ended up losing those two days of driving/studying driving myself. I passed, though my score dropped ~60ish points or so. I had another four weeks to finish studying for the USMLE and do as many questions as I could. I still didnt finish UW and I wish I would have. Finished up my studies and the last day or three of DIT 2 and managed to bump my USMLE score up ~20 points. Again, studying for USMLE =/= studying for COMLEX. The tests are different enough that you really need to use a COMLEX specific question bank for COMLEX. HOWEVER, using UW for content I think is a very good/controversial idea. Whether or not you take the USMLE, the tougher, more in depth and intricate questions will do nothing but be beneficial.
All IMHO, of course. But I'm going to be allowed to be a doctor soon.
