Short answer: the ELAC Debut 2.0 B6.2 for the higher ranking, the Polk Monitor XT20 for the lower price. The ELAC Debut 2.0 B6.2 ranks #32 of 47 bookshelf speakers at $479. The Polk Monitor XT20 ranks #35 at $279, $200 cheaper.
What the ELAC Debut 2.0 B6.2 gets right: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. The catch: A good size resonant peak around 700hz, directivity error around 3.3khz.
On the Polk Monitor XT20 side: Two-way bookshelf design with a 1” tweeter and 6.5” woofer. Set against that: Notably bright treble, elevated roughly 1-5dB above the midrange depending on frequency - a characteristic shared across the whole Polk XT.
Buy the ELAC Debut 2.0 B6.2 if the ranking matters more than the price. Buy the Polk Monitor XT20 if the price matters more than the ranking.

ELAC Debut 2.0 B6.2: $479.00 Crutchfield Amazon
Pros: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. Its larger-than-typical woofer lets it play very loud with minimal distortion, and minimum impedance stays a comfortable 5 ohms.
Cons: A good size resonant peak around 700hz, directivity error around 3.3khz. Predicted in-room response shows a lack of energy between 1-2kHz and a bit too much above that, which the reviewer thought would sound bright. Distortion at 96dB SPL/1m shows two harmonic peaks the reviewer says “should not be there,” one from woofer breakup around 400Hz and another around 7-8kHz from the tweeter. Cumulative spectral decay (waterfall) shows the same 700Hz resonance lingering. The reviewer needed EQ (taming the 700Hz peak, filling in the 1-2kHz dip, and trimming the highs) to get it sounding its best.

Polk Monitor XT20: $279.00 Crutchfield Amazon
Pros: Two-way bookshelf design with a 1” tweeter and 6.5” woofer, part of Polk’s budget-friendly XT lineup (spanning roughly $200-700 across the series). Measures more linear and has fewer/smaller cabinet resonances than its smaller sibling, the XT15, making it - by the reviewer’s own assessment - probably the better of the two based on data alone. Reasonably good bass output for the price and size, with an F3 of 63Hz. Horizontal radiation of about ±50° gives a respectable, enjoyable soundstage width. Takes well to EQ correction - the early-reflections directivity trend is decently linear, meaning tonal adjustments can meaningfully improve the sound. Provides usable, respectable volume when paired with a subwoofer crossover, even though it isn’t intended to play extremely loud on its own.
Cons: Notably bright treble, elevated roughly 1-5dB above the midrange depending on frequency - a characteristic shared across the whole Polk XT lineup, requiring either EQ or toe-out to tame. Small resonances appear around 300Hz and 800Hz, with some of that energy leaking from the port area. Vertical listening window is narrow - best kept close to the tweeter axis, with only a couple of degrees of tolerance above or below before the sound changes. Still needs a subwoofer for real low-end extension despite the decent F3. Overall linearity isn’t state-of-the-art flat, and while the reviewer found it pleasant, some artificial brightness remains even after basic EQ correction in the crossover region.
