I've worked on more than 10 different Scrum teams, and have seen it done well exactly once. When it was good, it was very good.
But we spent one entire workday (7 hours) on each sprint follow-up meeting, and then another entire workday planning the next sprint. That is what it took to write the stories, break them down into one-point pieces, prioritize with the PO, pass the stories out to the devs, etc.
Most places just don't plan for enough time to do things right, and quality is second priority, so no matter what methodology you use, you lose, because no cared about doing it right to begin with.
