Hg is easier to use for mainly 2 reasons:
1. The UI is more consistent ie. the "update" command only does 1 thing updates your working directory to a specified state.
2. It doesn't have a pre-commit staging "index" like Git (or it at least doesn't expose it to the user. So workflow is a bit for straightforward ie. you don't need to constantly "add" files before you commit, it automatically does it for you.
