I prefer meetings with just one clearly defined purpose that all participants agree is worth having a meeting for. Like "what are you currently working on?" (the daily stand-up), "what are we going to do this next sprint?" (the planning), "what is the best way to fix this problem we have?", "where do we want to be in 3 (or 6) months?".

As soon as there's more than one point on te agenda, the meeting is going to be a drag for half the participants.

(Of course that single purpose often still requires prep from the organiser and/or other participants.)
