Short answer: the KEF R5 Meta for placement freedom, the Revel F328Be for output. The R5 Meta’s 12th generation 5” Uni-Q coaxial array with Metamaterial Absorption Technology delivers remarkably smooth, controlled directivity that tracks off-axis almost identically, but its F3 of 52Hz and F10 of 38Hz need a subwoofer crossed over at 80Hz. The F328Be is quite flat with superb directivity and efficiency above 90dB.
Buy the Revel F328Be. It is rated higher for sound quality, and the KEF R5 Meta is discontinued, so it is only available used.

Revel F328Be: $19,359.90 per pair Crutchfield eBay
Pros: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. Predicted in-room response is extremely accurate, with a smooth ~5dB downward slope from bass to treble that suits typical rooms without correction. Early reflections sum very nicely with the direct sound. Horizontal beamwidth of about ±70 degrees is wide and quite smooth. At 96dB SPL/1m distortion stays easily below the reviewer’s audibility threshold across nearly the whole range. Measured bass extension of 74Hz (-3dB), with a measured sensitivity of 91dB.
Cons: Vertical directivity is asymmetric: the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis, reflecting the driver layout of this three-way tower. Impedance dips to a minimum of 3 ohms with an additional resonance-driven phase swing, calling for an amplifier comfortable with a demanding load. Very expensive and very heavy (51 kg each).

KEF R5 Meta: $3,999.99 per pair Discontinued eBay
Pros: 12th generation 5” Uni-Q coaxial driver array with Metamaterial Absorption Technology (MAT) delivers remarkably smooth, controlled horizontal (±50°) and vertical directivity with near-identical off-axis tracking. Exceptional frequency response linearity through the midrange and treble that takes extremely well to minor parametric EQ adjustments. Constrained Layer Damping cabinet construction and flexible rear ports minimize enclosure resonances and port turbulence. Deliberately tuned low-frequency roll-off profile permits boundary-adjacent room placement near front walls without boomy acoustic buildup. Measured bass extension of 52Hz (-3dB), with a measured sensitivity of 86dB.
Cons: Low-frequency extension (F3 of 52Hz, F10 of 38Hz) requires pairing with a dedicated subwoofer crossed over at 80Hz for high-output home theater or bass-heavy music performance. High-frequency radiation above 7kHz shows a mild on-axis taper (1-2dB downward slope), performing best when listened to 10-20° off-axis. Moderate sensitivity (~86dB SPL average) requires a clean, robust 4-ohm capable amplifier to drive high dynamic peaks without clipping. Discontinued.
