I still consider semver better. When it is used correctly, the version number gives a clear indication of what kind of changes to expect when upgrading. Obviously this is done to the best of knowledge of the author and might not always be 100% correct.

Either way, the amount of work to do for an upgrade depends on which parts of the product you are using and whether those parts have any changes in the new version. For this reason, most projects also have a changelog which gives you more detailed information about the upgrade. When preparing for an upgrade it is advised to read the changelog.
