Hamilton Incarnations (Workshop vs Mixtape etc)

I am a relatively new Hamilton fan and I know Hamilton went through many different drafts and workshops. In a nutshell, is there a huge different between:

Demos vs Workshop vs Mixtape and so on.

thanks!

I know that the workshop in Spring of 2014 ran over 3 hours (I wasn't there, but have talked to several people who were) and the final run time on Broadway is around 2.5 hours, so while I'm not sure exactly what was cut, there was about 30 minutes of material that was cut between then and the Broadway premiere.
