One think I havent read being mentioned on this thread is how Scrum discrete sprint units allow the dev team to focus in a task for some time.

I have been in both "sides" of scrum (dev and manager) and it is good not to have objectives changed every days. As a manager I even have had to split a scrum team in two (scrum and kanban) to maintain devs sanity.

Kanban is my preferred PMing process but only if there are defined "cutout" periods to perform releases or a CI/CD cycle.
