Short answer: the XTZ Spirit 4. It ranks #159 of 222 bookshelf speakers by sound quality, rated 3.4/5, at $477; the Sonus Faber Sonetto II G2 ranks #183, rated 3.1/5, and costs $3,500, so there is little reason to consider the other one.
What the Sonus Faber Sonetto II G2 does well: An Italian bookshelf speaker with a silk dome tweeter, a stylish concrete and metal base and evenly behaved dispersion. Watch for: Sounds notably bright pointed directly on-axis; toeing the speaker out about 30° reduces treble energy and sibilance meaningfully.
Why pick the XTZ Spirit 4: Stand-mount speakers with a waveguide tweeter, adjustable treble and port tuning, wide coverage and fairly deep bass. Watch for: The third-party measurement is low confidence.
Buy the XTZ Spirit 4. It is rated higher for sound quality than the Sonus Faber Sonetto II G2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
