Short answer: the Revel M106. It ranks #9 of 100 bookshelf speakers by sound quality; the KEF Q Concerto Meta ranks #11.
What the Revel M106 offers: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Watch for: Some directivity error and response variation shows up in the crossover region.
On the KEF Q Concerto Meta side: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Set against that: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
Buy the Revel M106 if sound quality matters more than the price. Buy the KEF Q Concerto Meta if the price matters more than sound quality.

Revel M106: Discontinued
Pros: CEA2034 spinorama shows a fairly even on-axis response with no obvious resonances, and a listening window that sits comfortably above the on-axis curve. Predicted in-room response is called “near ideal” by the reviewer, with a smooth downward slope from bass to treble. Distortion at 96dB SPL/1m stays well controlled through the midrange and treble.
Cons: Some directivity error and response variation shows up in the crossover region. Horizontal beamwidth of about ±50 degrees is on the narrower side. Vertical directivity requires staying within about ±20 degrees of the reference axis for accurate tonal balance. Minimum impedance dips to 4.6 ohms with several peaks, a moderately demanding load for a compact bookshelf speaker. Discontinued.

KEF Q Concerto Meta: $1,399.99 Amazon Crutchfield
Pros: Really good in-room neutrality with consistent horizontal directivity from seat to seat. Directivity holds remarkably steady from lower treble into upper treble, where many similarly-priced speakers narrow sharply as frequency rises - one of the reviewer’s top 10 picks under $1,500.
Cons: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment. Needs to be pointed closer to on-axis rather than heavily toed out - combined with its rolled-off, shelved-down top end, too much toe-out makes it sound noticeably dark.
