Pros: you don't need to load/maintain/tune a database; the Lua scripting makes it easy to pull features out of OSM tagging; free with no non-commercial restriction (OMT charges $2000 for a one-time commercial-use download of Europe, for example).
Cons: generating large areas require a lot of RAM; you can't just top it up with OSM diffs for the latest data; OMT has more corporate support; you don't get all the wizardry of PostGIS for geometry manipulation.
