Based off of patients I've interviewed, THC, CBD, CBDA, and THCA all have great pain fighting properties--it really depends on the individual and what you are using it for. In general CBD, CBDA and THCA need to build up in your system before you can get the best benefits. You might not feel anything right away with those types of products.
