I don't disagree about Benetti's attention to non-game-related topics, such as ballpark activity, music tastes, long sidebars on pop culture only millennials really understand, things along those lines. I do find that somewhat annoying at times—not always, but sometimes—as it leads to his too-cute-by-half bon mots that I think are rather polarizing (since some fans love love love those).
What Benetti is far better than Mario at is talking about the actual game in progress and providing insights on it. Despite his penchant for ghosting his daytime job to go call football games, Benetti is a real baseball guy and he does know the game well. Mario could not provide insights on games to save his job, which is probably why he doesn't have a job right now, and in fact hasn't had one since the Red Sox let him go after the 2019 season. If Mario were actually good at calling baseball games, he'd be doing that for a living right now.
