What is the difference between OpenTSDB and Graphite?

As far as I can tell, here are the main differences:

OpenTSDB does not deteriorate data over time, unlike Graphite where the size of the database is pre-determined.
OpenTSDB can store metrics per second, as opposed to Graphite which has minute intervals (I'm not sure of this, Graphite docs show retention policies which stores metrics every minute, but I don't know if this is the minimum unit of time we can play with)

I want to make an informed decision about which tool to use in order to store metrics, have I missed any other differences in these 2 systems? How performant/scalable are they?

Bonus Question: Is there any other time series system I should look at?
