I've often found that the insight I get from an algorithm's complexity is not a complete picture of its worthiness for a particular problem, but it is almost always a necessary piece of the puzzle. I would never feel confident using an algorithm that I'd only empirically measured on some number of hand-chosen datasets because then who knows how it will behave when a user throws something unexpected at it.
