I would say RJJ as well. If it was 1985-1995 then I would say Whitaker. In my opinion Whitaker was at his peak in the late 80's. I agree that Holyfield and Tszyu should at least be part of the discussion.
I'll go with RJ. Whitaker did have his best wins in the early 90's but as mentioned he did fade a bit later in the mid to lated 90's, while Roy owned the entire decade.
Tyson's a legend...not just in boxing but, a REAL legend....he will forever be remembered in the public.....plus he was a monster in the ring in his prime so i voted for Tyson....though the more reasonable choice would probabbly be Roy Jones
exciting and best are 2 different things...cant be both whitaker was far from exciting .... but was one of the best
id say rjj best fits the criteria, exciting and best id probably have whitaker next, if only he had more power he would of been more exciting any tyson fight,there was always an air of excitement, even though the 90's wasnt hes best time lewis dont deserve to be there , exciting or best
