It’s much much better with moved code.
Delta adds color to the standard git diff algorithm.
Omnidiff uses a completely different algorithm.
About a third of diffs are significantly better.

Git will highlight moved code and delta shows that, so how does OmniDiff differ from
git diff --color-moved=zebra --color-moved-ws=allow-indentation-changeThe default git diff uses the Myers diff algorithm as implemented in xdiff. It's a line based diff with some pre and post processing for better results.
The move detection is a post-processing step that only works on lines and additionally only works if you also enable coloured output.
It can't match "moved-but-eddited" code and it can't match "this one log line was copied 3 times in the new code" or the refactoring equivalent "these 2 blocks of code were merged into one reusable function".
You have to use more syntax-aware algorithms to get true move detection. OmniDiff matches the nodes of the AST to get some of that syntax awareness.
