One would expect MANY threads to have covered this, but you might have to be careful with the wording used in your search.
That said, I really liked First Aid for Step 2 CK. I think it covered most topics very well. I used Deja Review to fill in some of the gaps. I, personally, liked QBank (Kaplan) more than UW. Most people choose UW, though the lower cost may be a factor. First Aid for Step 2 CK is used to prepare for the USMLE Step 2 CK exam. First Aid for the Wards is used for M3 during Clerkships, as is Boards and Wards. FA for the Wards and Boards and Wards are separate items.
I would agree with what you said about the Kaplan books. They are too lengthy and I would not recommend using them for Step 2. Good luck!!
