If planet.c is truly quicker then it makes sense to use it. osmosis is
including user information in the dump which I thought would be useful
but that should be easy to add to planet.c as well.
I've done my best to make osmosis as flexible as possible for a wide
range of usage scenarios, I was hoping it could become a universal tool
for shifting OSM data around. While there's no harm in having competing
tools for the same job, it does raise the issue of maintaining all of
these tools when the schema changes however ...
At the end of the day I don't really mind which tool is used. osmosis
is aiming to eliminate planet dumping altogether, how we get there
