The question might be less about where to place the climax than how to keep listeners engaged. I attempt to create interest as a song progresses in several ways. Could be new instrumentation, a harmony, a bridge, a pre-chorus, a key change, a BGV, a lyrical twist, etc. It just has to be fun to listen to and serve the song. On the example in the OP, I was saving two cool sounding alternative readings of the title line for the outro. Songs like My Best Friends Girlfriend always keep me until the end because I love the new ways he finds to sing the title line as they wrap it up. I can think of dozens of songs that don't do this that I love just as much though. So it depends.
But I do love it when someone is listening to the final note and says, "That's SO cool..."
