The best solution will really depend on your environment. What is the topology like? I would avoid MST/MSTP unless you have a good reason to use it. A Cisco running MSTP should interoperate with non-MSTP-speaking devices, as external to MSTP-speaking boxes, each "region" looks like like a big spanning-tree bridge. If your environment is simple and doesn't have any unusual requirements, I would go for rapid-pvst/rstp on each device.
