Short answer: a tie on sound quality. Both are rated 4.3/5 (#11 and #8 of 178 bookshelf speakers), so choose on features and fit.
The Aalto Speakers Aalto 1 EVO is the more accurate, deeper-bass option. Excellent local Spinorama results for a very compact passive speaker: 5.92 raw and 8.25 with a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 5.92 against 3.38 for the Arendal 1961 Monitor. Its bass reaches about 47.4Hz before falling 10dB, against 60Hz for the Arendal 1961 Monitor. The tradeoff: Low 81.5dB sensitivity and a 3.3-ohm minimum impedance demand a capable amplifier.
What the Arendal 1961 Monitor does well: A robust sealed monitor with two 5.5” woofers that delivers low compression, low distortion and really good overall neutrality. The tradeoff: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well.
Buy the Aalto Speakers Aalto 1 EVO or the Arendal 1961 Monitor 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.
