MLSE will be the popular choice amongst Canadians mostly because 90% of Canadians (myself included) have a distaste for Bell and Rogers. Americans wont get it, but in summary they are 2 of the richest telecommunication companies in the world built on monopolizing the market in Canada ripping of the population who has no other option. Amongst the highest prices in the world, they are also 2 of the few direct competitors in any market that actually RAISE prices relatively to each other rather than drop to be competitive.
However, with the rant said, they have been nothing but great on the sports side of things. Since they purchased MLSE the Leafs, Raptors and TFC have all been competitive.
