I quite liked the PDP-11 (we ran Unix on a /40 and a /45), and thought the 
VAX-11
(Unix on a /780 and a /750) was generally better; neither would rate as 
favourites.

I agree with the nominations of the Ferranti Pegasus, and of the MU5/ICL 
2900;
and propose the very different English Electric KDF9:

People tend to focus on the arithmetic stack of the KDF9.
In my view the hardware multiprogramming support and the
internal parallelism are more significant advances.

BTW None of these was the first computer I used.
That was an ICT/ICL 1903. I like that too. 8-)
