Short answer: a tie on sound quality. Both are rated 4.7/5 (#11 and #12 of 119 powered bookshelf speakers), so choose on features and fit.
What the Aalto Speakers Aalto 3 Active Pro does well: The manufacturer dataset reports a remarkably even 0.7dB response span from 300Hz to 5kHz, 34.6Hz -3dB extension and an 8.90 ideal-subwoofer preference score. The tradeoff: External amplification and system setup make this less straightforward than a self-contained desktop pair.
What the Buchardt A10 does well: The measured tuning combines 31.5Hz -3dB bass extension with preference scores of 7.28 standalone and 8.00 with an ideal subwoofer. The catch: The rising treble balance can sound brighter on axis; toe-out or a different tuning may suit some rooms.
Buy the Aalto Speakers Aalto 3 Active Pro or the Buchardt A10 on features: they are rated the same for sound quality at close to the same price.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared. The two were measured by different sources, so small differences, especially in the bass, can come from the measurement setup rather than the speakers.
