I am definitely more productive on the 6 week cycle, the 2 week cycle was too much overhead and friction for me, however I do recognize that some individuals (who were more senior than me) were more productive after our org. transitioned to the 2 week cycle, although I suspect this was more a result of higher oversight/scrutiny in their day to day more than anything. I tend to view the work that I do as more engineering than it is development, frequently having to pull out the paper and math it out, so I think the problems I tend to work on are just fundamentally more difficult to corral into 2 week estimation chunks, but that could just be ego talking. When I started making investigation/research its own estimate that helped a bit. I think it's harder to investigate, justify, and perform significant refactors (or rewrites) on the 2 week sprint cycle, but not every team needs to do that all the time.
