Flown a lot of Boeing stuff - but the 737-300 I like the most.
Liked the 777. liked the 757 and like the 737 NG - don't like the A320/319.
I liked the 737-200 in many ways apart from the fact it would go down like a brick but wouild climb like mule.
The 747 I can't comment on as I ever only operated as F/E - however from my perspective in that seat it was a worldbeater.
