usually use the -p flag with a git checkout from the other branch which I find easier and more granular than most other methods I have come across.

In principle:

git checkout <other_branch_name> <files/to/grab in/list/separated/by/spaces> -p
example:

git checkout mybranch config/important.yml app/models/important.rb -p
You then get a dialog asking you which changes you want in "blobs" this pretty much works out to every chunk of continuous code change which you can then signal y (Yes) n (No) etc for each chunk of code.
