High stats don't make characters heroic -- actions do.
For the record, I've had fun using anything from 25 to 36 point buy, and anything from 3d6 in order to 5d6, drop lowest 2. And arrays, auctions, choosing. And a couple of other ways.
Yet I still think there is something to what some people say, along the lines of higher stats being "heroic". I know it's not absolutely accurate, in strict terms. But I think it's just shorthand for saying that higher stats better enable PCs to do epic/heroic things -
and to live through those experiences at least once or twice (preferably more).
Larger than life, high powered, grand, epic, heroic. The lines (or definitions) blur for some people. It think that is essentially what that's all about.
At the moment, for what it's worth, I use a custom point-buy system, which allows for a greater potential starting range of ability scores than the DMG's. With the level I have it set at currently, it probably works out to be the equivalent of around 32 points in the standard system, I think. So, "high power" perhaps. I generally quite like games set around that level. There is no good reason a PC shouldn't have an 18 without being hamstrung every which way elsewise, for example. IMO.
