Type F or Dexron, why do some HP guys dislike type F

I have been using Type F for some time now. A comment on 904's being weaker and less reliable at least in my case is totally wrong! I rebuilt mine in 2000 and was driven daily for two years and then been driven like hell (not daily) the last 8 years and I still have had no problems! That was the first tranny that I ever did!
