Short answer: the KEF R11 Meta on measured sound quality, the SVS Ultra Evolution Pinnacle on price. The KEF R11 Meta ranks #44 of 188 floorstanding speakers, rated 4.4/5, at $6,999.98. The SVS Ultra Evolution Pinnacle ranks #125, rated 3.8/5, at $2,499, $4,500.98 cheaper.
The R11 Meta is the more accurate tower. Audio Science Review found a generally flat on-axis response, a very smooth predicted in-room response apart from a small 1 to 1.5kHz dip, and bass reaching 31Hz before falling 10dB. Its coaxial Uni-Q driver gives unusually even vertical dispersion for a tower, and distortion stays very low even at 102dB. Its impedance dips to 3.2 ohms, so pair it with a capable amplifier.
The Ultra Evolution Pinnacle is a huge three-way with very deep bass. Four 8-inch woofers, two 5.25-inch midranges and a diamond-coated tweeter reach 41Hz before falling 3dB, with broad horizontal coverage of about 75 degrees each side and 88.1dB sensitivity. A dip and peak around 2 to 3kHz give vocals a forward, shouty quality, and at 96.8 lbs (43.9 kg) each they are hard to position.

KEF R11 Meta: $6,999.98 per pair Amazon eBay
Older model: the KEF R11 (ranked lower, estimated 4.3/5).
Same family: the KEF R3 Meta (bookshelf, rated 4.6/5), the KEF R5 Meta (smaller floorstanding, ranked higher, rated 4.6/5), the KEF R7 Meta (smaller floorstanding, ranked higher, estimated 4.6/5), the KEF R2 Meta (smaller center, rated 4.3/5) and the KEF R6 Meta (larger center, rated 4.2/5).
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. Measured bass extension of 64Hz (-3dB).
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.

SVS Ultra Evolution Pinnacle: $2,499.00 per pair Amazon SVS eBay
Same family: the SVS Ultra Evolution Nano (smaller bookshelf, estimated 3.9/5), the SVS Ultra Evolution Bookshelf (larger bookshelf, estimated 4/5), the SVS Ultra Evolution Tower (smaller floorstanding, ranked higher, estimated 4.1/5), the SVS Ultra Evolution Titan (smaller floorstanding, ranked higher, estimated 4.2/5) and the SVS Ultra Evolution Center (center, estimated 4.1/5).
Pros: Flagship three-way tower with a diamond-coated tweeter, dual midranges and four force-balanced 8-inch woofers. Erin measured exceptional 27Hz extension, broad roughly +/-75-degree horizontal coverage, an 88.1dB sensitivity and a 4.91 preference score even without a subwoofer. Measured bass extension of 41.0Hz (-3dB).
Cons: The 5.25-to-8-inch transitions and complex array do not produce class-leading smoothness: 0.184 on-axis, 0.226 predicted in-room and 3.64 directivity-index consistency. At 96.7 pounds each, these are difficult to position, and their Q of 1.25 indicates some bass emphasis. A dip in the upper midrange followed closely by a peak around 2 to 3kHz gives vocals a shouty, forward quality that toe-out alone does not resolve.
