I - as a forever DM - agree with Matt, but I've found that with my players, they generally want an Epic.
Both groups have lamented shorter campaigns and adventures. My preference would be a 10-session mini campaign with a direct goal. Then we can move on to a new story, new setting, etc.
My players want multi-year long adventures. One told me, "I feel like I can't get into my character until the 10th session"; almost all have loved the story of that D&D group that's played the same campaign for 40 years
