In my career so far, I've most enjoyed working on kanban-esque teams. Just a bunch of tickets, maybe sorted by priority, for anybody to jump on. A wireframe to reference and quick slack updates once a day. Ironically, this was my least favorite job, but the working style has turned out to be my favorite.

Since then I've worked on agile teams and found it to be less useful. I'm sure there are reasons for why, but strictly from a personal point of view, it's much more fun and relaxing to just do kanban.
