The safest ending is surely a long fade out. You don’t even notice the song is over until the next track drops.
The most impressive way to end is the crisp, hard out. One final chorus and the song ends hard on the last note. Planned, practiced, with the whole band finishing on the same beat.
But sometimes improvisation and competing solos take over, and the only way out is a classic trash can ending.
