Short answer: the Q Acoustics 3010c. Both are rated 3.4/5 for sound quality (#76 and #77 of 168 bookshelf speakers), and the Q Acoustics 3010c costs $479 against $1,199.98 for the KEF Q4 Meta, so with nothing between them on sound quality, price settles it.
What the KEF Q4 Meta does well: A slim on-wall speaker, 14.2cm deep, built around KEF’s 5.25” Uni-Q driver with a 1” vented aluminium tweeter and Metamaterial Absorption Technology. Watch for: KEF’s data is not valid below 200Hz, so it has no preference score; the rating is estimated from it and the measured KEF Q3 Meta.
Why pick the Q Acoustics 3010c: Ultra-compact bookshelf speaker utilizing the C3 Continuous Curved Cone 4-inch mid/bass driver and a hermetically sealed 0.9-inch decoupled high-frequency unit. The tradeoff: Rating estimated based on 3000c series sibling testing.
Buy the Q Acoustics 3010c. Both are rated the same for sound quality, and it costs $720.98 less than the KEF Q4 Meta.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: KEF Q4 Meta 3.0 to 3.8; Q Acoustics 3010c 3.2 to 3.6). Treat this verdict as provisional.

Same family: the KEF Q1 Meta (smaller bookshelf, ranked higher, rated 3.6/5), the KEF Q3 Meta (larger bookshelf, rated 3.4/5), the KEF Q Concerto Meta (larger bookshelf, rated 4.6/5), the KEF Q7 Meta (smaller floorstanding, estimated 3.5/5), the KEF Q11 Meta (larger floorstanding, rated 4/5), the KEF Q6 Meta (center, rated 3.9/5) and the KEF Q8 Meta (surround, rated 3.4/5). See every KEF Q Series generation.
Pros: A slim on-wall speaker, 14.2cm deep, built around KEF’s 5.25” Uni-Q driver with a 1” vented aluminium tweeter and Metamaterial Absorption Technology. It works as a left, center, right or surround speaker. KEF’s own measurements show smooth sound power. Measured bass extension of 40.5Hz (-10dB).
Cons: KEF’s data is not valid below 200Hz, so it has no preference score; the rating is estimated from it and the measured KEF Q3 Meta. KEF rates the bass to 65Hz (±3dB), so it needs a subwoofer for full-range music. Impedance dips to 3.2 ohms.
