Short answer: a tie on sound quality. Both are rated 4.7/5 (#4 and #3 of 15 powered floorstanding speakers), so choose on features and fit.
The Aalto Speakers Aalto 9 is the more accurate option. Manufacturer measurements give it a 8.24 preference score without a subwoofer and 8.84 with an ideal one, the highest standard score of any speaker we list. Its measured preference score, a predictor of how neutral it sounds, is 8.24 against 6.61 for the GGNTKT M3. The catch: The data is the manufacturer’s own and spinorama rates its quality as low, so the scores lack independent confirmation.
The case for the GGNTKT M3: The manufacturer measurement shows a very tight 0.5dB response span from 300Hz to 5kHz and a 8.59 ideal-subwoofer preference score, supporting exceptionally even midrange balance. The tradeoff: Measured -3dB extension of 35.5Hz is useful but does not match the deepest-reaching towers here.
Buy the Aalto Speakers Aalto 9 or the GGNTKT M3 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.
