Back in June 2001, I had decided that I didn't want to be associated with the JWs or the Watchtower (my mother became a JW back in the early 1970s when I was 4. At the time I had written a DA letter, but I didn't send it in, because I was attempting to fade out of the religion. The main thing I brought up was how the Watchtower has shown itself as a false prophet. My mother became a JW because they had lied to her and actually told her that in the fall of 1975 it would be the end of this system of things, and she would be reunited with her baby girl who had died a couple of years before that.
It was my brother in law who pushed the issues, and it came down to either being DF (was checking out a church) or DA myself. Looking back there were things I wished I had done differently, but it's too late now. I don't regret sending in my letter, because it did, for the most part put an end to the mind games that my dysfunctional JW relatives were playing on me.
The ExJW Critical Thinker on Youtube does have some very helpful information regarding this decision, and it was something I really wished I had known when I made this decision. Here is a link to a few of those videos.

These are a couple, but they have others you can also check out. I hope you can find some helpful information to help you to make the best decision for you.
