Re: Sorry, but ...
"There are only two Doctors of note ... Jon Pertwee and Tom Baker. All others pale into insignificance."
I don't think that there is or ever can be a 'best' Doctor.
Believe it or not, Doctor Who was a very serious programme when it first started and William Hartnell was the perfect first Doctor, irritable, intolerant and impatient. You didn't like him but you respected and feared him.
Tom Baker's Doctor, on the other hand, was relaxed, affable, whimsical and very likeable. Humour, something not really present with the earlier Doctors, began to feature.
In hindsight, Jon Pertwee's Doctor, along with Patrick Troughton's, turned out to be somewhat transitional characters.
