In general, for local stuff, rebase is to be preferred. It leaves a nicer git history. 

### Merge
git checkout branch_you_want_to_merge_changes_into   
git merge branch_whose_changes_you_want

### Rebase
git checkout branch_whose_changes_you_want    
git rebase branch_you_want_to_rebase_changes_into
