Short answer: the Devialet Phantom II 98 dB for better sound quality, the Genelec 8020D for the lower price. The Devialet Phantom II 98 dB ranks #9 of 65 powered bookshelf speakers at $2998. The Genelec 8020D ranks #11 at $695, $2303 cheaper.
What the Genelec 8020D offers: A compact waveguided monitor with balanced XLR input and placement filters, well suited to a small studio desk. Watch for: Small size limits deep-bass reach and headroom. It lacks the GLM calibration of the SAM models, and the price is substantial for a compact analog-input monitor.
What the Devialet Phantom II 98 dB offers: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Scores of 6.07 standalone and 7.15 with an ideal subwoofer suggest that its appeal is not limited to bass quantity. Integrated amplification and network playback can replace several components, and its 2.3dB midrange response span is reasonably even. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume. Stereo requires two units, and the integrated architecture offers less system flexibility than conventional monitors.
Buy the Genelec 8020D if the price matters more than sound quality. Buy the Devialet Phantom II 98 dB if sound quality matters more than the price.
