Yes good points. For me the greatest win is actual buyer anonymity, whereas even Monera and other privacy centered coins were found to be vulnerable to traceability.
Also it would be terrible to have such opaque blockchain coins as mainstream. Tax evasion, illegal/dark activities and speculation are enabled.
Also I fell that the motivation of the people behind GNU Taler is 'good'. It does not smell like venture capital / hype / speculation.
Feels like they try to create a solution that actually reflects the needs of normal people.
