I was not around for JH as Manager, but for all he has done for CCFC and football, I would choose him, but not far behind would be Snoz and George, purely for those few months when my club was the center of the world, Wogan, Blue Peter, Central, BBC, Go for it CITY...everyone wanted a bit of the Sky Blues...and as an all time John'Jock'Stein the first British manager to lift the European Cup with a British Team (Champions League for the younger peeps) Celtic won the EC with a team of players that all came from Scotland and 9 of them were born within 9 miles of Glasgow, he signed Catholics and Prodestants - he was a Prodestant, and overcame the bitter sectarianism that was rife in Scotland in the 60's, he was an innovator in tactics, and studied opposition teams and formations, took this on the the training pitch and drilled his team into how to beat them, this is done today at all clubs, but in 1960 was unheard of apart from the great Helenio Herrera who Stein studied at close range...sorry to go on but he was a great, like Shankley, Buzby, Paisley, Ferguson.
