In my personal experience, a lot of the coolest at-the-table gaming moments for me and my various groups have been when we've rolled the dice and either come up with an incredible success because of it (amazed looks on everyones' faces at the huge number of successes) or succeeded with a catch that had to be resolved later (sometimes cringe-worthy but hey, overcoming the challenges can be as memorable as amazing, seemingly-effortless success).
I don't like to be in the position of thinking "so why did I spend all that XP on N, when the GM just lets us get away with resolving all or most N-related tasks narratively, without involving the mechanics I chose to buy in to?"
