I guess this is probably a subjective topic, but I quite like they way Assembla handles it's Merge Requests.

When you make a change, all your new commits show up in a new version, and you can switch between the different versions of the MR to see the old state of the code before each new version. Where a version is created after a push of new commits to the branch.

You still keep the entire commit history (which I much prefer), but the view of that history and discussion around it is much clearer in the MR.

Github's way of doing it makes it difficult to see a concise view of the history of the MR, which can contain very valuable information outside of the commit history.
