Well, I'm not one to go with the "either/or" decision.. On papers I usually write "proposition A is better, however it needs these parts from proposition B". I'm "the Apostle of Compromise." (Wouldn't I make an awesome diplomat?)
Anyway, I'd have to say Timmie's coffee is the worst coffee in existence, except for the pretend coffee you find in ratpacks. Now, I'm not talking about iced caps or anything like that--most of their ultra-sugary stuff is decent.
But for specialty coffees, lattes and whatever else you might want including your basic coffee, Starbucks is far superior. Any coffee from Starbucks would beat all of Timmie's offerings, even if they threw in a Boston Creme donut.
As for donuts, I think it's obvious that Krispy Kreme is so far ahead of Timmie's there's no need to debate. The only problem is that it causes instant death in diabetics.
