It's pretty simple... readability triumphs. It's a hell of a lot easier examining the history of a project if a feature is condensed into a single or a few easy to read commits. Your personal struggle to implement a feature is far less important than having a clear, readable history. This becomes super important when bisecting, reverting, generating release notes, and a myriad of other things.
It's pretty simple... You can maintain an accurate history of commits while using tags to have a clean list of features and/or releases. A clean history of features or releases does not require rebasing.
