Meld might be useful for comparison, but in my opinion it is inconvenient as a git merge tool. For git merge I need four panels: original file, version A, version B, merged result. Meld has only three panels.
Currently I am using KDiff3. It is a little buggy and doesn't have a nice UI but it is the best open source merging tool that I am aware of. It allows choosing lines from original file, from A, B and manual editing.
I noticed that certain popular and highly praised commercial IDE also provides only 3-panel interface for merging. This makes resolving conflicts more difficult and prone to errors.
