Short answer: a tie on sound quality. Both are rated 3.6/5 (#40 and #37 of 89 bookshelf speakers) at nearly the same price ($699.99 vs $699), so choose on features and fit.
What the KEF Q1 Meta does well: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. Watch for: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies.
The case for the PSB Alpha P5: Well-behaved 5.25-inch bookshelf design with excellent 0.113 on-axis smoothness, a nearly flat +0.12dB/octave slope and broad roughly +/-60-degree horizontal coverage. The tradeoff: Measured sensitivity is low at roughly 84dB, and the underdamped bass alignment (Q 0.42) trades some weight for control.
Buy the KEF Q1 Meta or the PSB Alpha P5 on features: they are rated the same for sound quality at close to the same price.

Older models: the KEF Q150 (rated 3.7/5) and the KEF Q100 (rated 2.4/5).
Pros: 12th generation Uni-Q coaxial driver places the 1” vented aluminium dome tweeter at the centre of the 5.25” aluminium woofer, with KEF’s Metamaterial Absorption Technology behind the tweeter. KEF’s own Spinorama measurements, published on spinorama.org, hold the 300Hz to 5kHz response within 2.3dB with a flat on-axis trend, so the tonal balance is even. Measured bass reaches 65Hz (-3dB) and about 43Hz (-10dB), respectable for a compact bookshelf. Same cabinet size as the Q150 it replaces. Measured bass extension of 65.1Hz (-3dB).
Cons: The only measurements are KEF’s own, not independently verified, and spinorama.org computes no preference score for them because the data is truncated at low frequencies. Sound power directivity is less even than the best in this class (3.16dB index deviation), so off-axis listeners and room reflections shift the balance more. Minimum impedance of 3.2 ohms is a harder load than the Q150’s, and rated maximum output is a modest 108dB, so plan on a subwoofer for loud listening.

PSB Alpha P5: $699 per pair PSB Speakers eBay
Pros: Well-behaved 5.25-inch bookshelf design with excellent 0.113 on-axis smoothness, a nearly flat +0.12dB/octave slope and broad roughly +/-60-degree horizontal coverage. ASR data predicts a 6.25 preference score with a subwoofer and 48Hz in-room extension. Measured bass extension of 58.6Hz (-3dB), with a measured sensitivity of 87dB.
Cons: Measured sensitivity is low at roughly 84dB, and the underdamped bass alignment (Q 0.42) trades some weight for control. Directivity-index consistency is middling at 3.67 and the raw no-subwoofer preference score is only 3.99.
