Short answer: the Revel F328Be for the higher ranking, the KEF R11 Meta for the lower price. The Revel F328Be ranks #5 of 25 floorstanding speakers at $13600. The KEF R11 Meta ranks #7 at $3499.99, $10100.01 cheaper.
On the KEF R11 Meta side: CEA2034 spinorama shows a generally flat on-axis response with good directivity and very deep bass extension (F10 of 30Hz). Set against that: A dip around 1-1.2kHz on-axis is attributed to a diffraction effect, and shows up as a smaller dip in the predicted in-room response.
The case for the Revel F328Be: CEA2034 spinorama shows a quite flat on-axis response with superb directivity and efficiency above 90dB. The catch: Vertical directivity is asymmetric - the reviewer recommends staying between -20 and +40 degrees relative to the tweeter axis.
Buy the KEF R11 Meta if the price matters more than the ranking. Buy the Revel F328Be if the ranking matters more than the price.

The Two Speakers In Full
KEF R11 Meta: $3,499.99 Amazon
Pros: CEA2034 spinorama shows a generally flat on-axis response with good directivity and very deep bass extension (F10 of 30Hz). Predicted in-room response is very smooth aside from the small 1-1.5kHz dip. The coaxial Uni-Q driver gives excellent, symmetric vertical directivity, unusual for a tower speaker. Distortion is incredibly low even down to 30Hz at 86dB SPL/1m, and stays low even at 96dB and 102dB SPL/1m - the reviewer found essentially no audible tonality change across that whole output range.
Cons: A dip around 1-1.2kHz on-axis is attributed to a diffraction effect, and shows up as a smaller dip in the predicted in-room response. Horizontal beamwidth of about ±40 degrees is on the narrower side, though the transition from wide to constant directivity is smooth. Minimum impedance dips to 3.2 ohms around 580Hz, calling for an amplifier comfortable with a demanding load. 4-ohm nominal impedance overall.

Revel F328Be: $13600 Crutchfield
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.
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).
