Short answer: the KEF Q Concerto Meta. It ranks #11 of 203 bookshelf speakers by sound quality (rated 4.6/5) at $1,399.99 and is still sold new; the Revel Performa M22 ranks #151 (rated 3.3/5) and is discontinued, so it is only an option used.
The Revel Performa M22 is the deeper-bass choice. Very flat frequency response from 200Hz to 10kHz. Its bass reaches about 46.9Hz before falling 3dB, against 53Hz for the KEF Q Concerto Meta. The tradeoff: 3dB bass boost around 100Hz.
The KEF Q Concerto Meta is the more accurate option. Really good in-room neutrality with consistent horizontal directivity from seat to seat. Its measured preference score, a predictor of how neutral it sounds, is 6.01 against 5.31 for the Revel Performa M22. The tradeoff: Radiation pattern measures about ±50°, narrower than the reviewer’s preferred ±60° for a stronger sense of envelopment.
Buy the KEF Q Concerto Meta. It is rated higher for sound quality and still sold new, while the Revel Performa M22 is discontinued.

The Two Speakers In Full
Revel Performa M22: $600 per pair used (about) Discontinued eBay
Same family: the Revel Performa C52 (center, rated 4/5).
Pros: Very flat frequency response from 200Hz to 10kHz. Distortion is well controlled through most of the range, with only a modest crossover-region bump around 2-4kHz. Measured bass extension of 46.9Hz (-3dB).
Cons: 3dB bass boost around 100Hz. On-axis response also droops below 150Hz and peaks above 4kHz, which the reviewer thought may sound a bit bright/light. Distortion rises substantially below 100Hz when driven hard. Discontinued.

KEF Q Concerto Meta: $1,399.99 per pair Amazon Crutchfield eBay
Same family: the KEF Q1 Meta (smaller bookshelf, rated 3.6/5), the KEF Q4 Meta (smaller bookshelf, estimated 3.4/5), the KEF Q3 Meta (smaller bookshelf, ranked lower, rated 3.4/5), the KEF Q7 Meta (smaller floorstanding, estimated 3.5/5), the KEF Q11 Meta (larger floorstanding, rated 4/5) and the KEF Q6 Meta (center, rated 3.9/5).
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. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 84.2dB.
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.
