I'll bite: I am not a huge fan of pitchers duels or extremely close ballgames.
First, if it's a game I have a rooting interest in, they are incredibly stressful to watch. Knowing that the game could be decided by any one pitch, I must hang on to every single moment of every single AB. If I go to the restroom, go to get a hot dog, or my family wants something from me, I could miss the game-defining moment.
Second, even if I don't have a rooting interest (but especially if I do), the outcomes of close games always seem arbitrary or even unfair. These games are often won on pure luck: by one ground ball just missing the shortstop's glove, by one hitter pounding a single hung slider, even by one borderline ball/strike call going a particular way. The losers get to seethe and complain about the one thing that did them in, but the victors often also feel like "oh wow, we got lucky". Compare a 12-8 ballgame where the difference was made by a lot of different things and no one factor dominates.
So yeah give me a slugfest anytime over a tight pitcher's duel. Give me something like the 2007 tiebreaker game between the Rockies and the Padres, or the Field of Dreams game this year.
