Im gonna have to go with Paul Grundy (founder of JWFacts.com).
Lloyd Evans (aka John Cedars) is very good with his research and videos but JWFacts.com has all the research on there. Unlike Lloyd Evans, Paul Grundy is an ex-Bethelite so has that first hand experience, he went to the trouble of researching and presenting the content very well and creating the site not for monetary gain but just to put the information out there.
With Lloyd Evans, i do like his stuff, but i understand why some people dont take to him. I dont like that he plugs his book at the end of each video, i dont like that his book is overpriced and i dont like that in his new book he offered to let you tell your story... for a fee!
Ray Franz did sell his book but i dont hold that against him. The guy had no pension or savings due to serving Watchtower all his life.
