Short answer: the GR-Research X-LS Encore for the higher ranking, the ELAC Debut 2.0 B6.2 for the lower price. The GR-Research X-LS Encore ranks #28 of 47 bookshelf speakers at $1300. The ELAC Debut 2.0 B6.2 ranks #32 at $479, $821 cheaper.
The case for the ELAC Debut 2.0 B6.2: Reasonably flat on-axis and listening-window response with reasonably even horizontal directivity. Set against that: A good size resonant peak around 700hz, directivity error around 3.3khz.
What the GR-Research X-LS Encore gets right: An amazing value, especially if you managed to snag one of these built by AV123 in the early 2000s for $200-300. CEA2034 spinorama shows. Set against that: A slight depression in the upper bass and some peaking in the lower bass shows up on-axis.
Buy the ELAC Debut 2.0 B6.2 if the price matters more than the ranking. Buy the GR-Research X-LS Encore if the ranking matters more than the price.

The Two Speakers In Full
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.

GR-Research X-LS Encore: $1300 Gr-research
Pros: An amazing value, especially if you managed to snag one of these built by AV123 in the early 2000s for $200-300. CEA2034 spinorama shows a generally flat on-axis response, especially in the listening window. Predicted in-room response is generally smooth and on-target. Distortion at 86dB SPL/1m is pretty clean above 200Hz.
Cons: A slight depression in the upper bass and some peaking in the lower bass shows up on-axis, along with directivity error in the crossover region. Vertical directivity requires staying within about 20 degrees of the tweeter axis. At 96dB SPL/1m distortion becomes “rather unhappy,” with bass distortion, a possible woofer issue around 2kHz, and a tweeter problem above 7kHz. As a DIY kit, it requires building the cabinet and crossover yourself.
