To be absolutely faire and honest, you must not forget that when Intel released the P3 1.13GHz, every sites except Tom's said it was a nice chip. Tom got accused of being a biased pro-AMD guy. Yet, 1 month later, it appeared that HE was right, and that every other reviewers just accept what they were given from Intel without any questions.
When the P4 was launched and everybody laughted at it, Tom was the first to show benchmarks of what it "could" look like in the future with software optimization.
When Intel sealed the deal with Rambus in 1999, every review sites were claiming that Rambus technology was the way to go and it was the "only" way to bring memory to such high bandwith (I admit it, I wasn't reading Anandtech at the time...), except for Tom who was claiming that DDR would be better, for less money. Once again, he was accused of being a fanboy of AMD.
I just think that most of his opinions often turn out to be true. Tom is strong worded and arrogant for sure, but clearly sitting with Anand at the top of the "reviews world"
