Another good spat was between Stephen Hawking and Leonard Susskind and a bunch of other researchers. The way Susskind tells it is hilarious. Hawking would sit in his little chair all indignant yelling "rubbish" in his electronic voice.
I forget what they were fighting over. Information conserved about objects that fall into black holes as 2-D holograms around the radius....I think.
Anyway, if you can find something on Youtube where Susskind tells the story it is pretty good.
.......And science moves on.........
