Sets of one long rep or sets of short reps?

Not that I'm choosy, it's just that we all have our methods, but I would go for a workout divided into long reps only, even though it's no longer your average multiple reps within sets, until I can't lift anymore, which then depends on the weight hanging on the dumbbells because, the heavier the shorter, but basically, when referring to a long rep training, I'm talking about a number comprised between sixty and eighty ups and downs. The idea of taking a break between reps in order to complete a set just isn't what I prefer. As a matter of fact, I'm only content when my muscles feel tired and sunburnt while attaining muscle failure before moving to an another kind of exercise.

So, I'm wondering what your preference is like?
