Short answer: the KEF Reference 203 for better sound quality, the Revel F206 for the lower price. The KEF Reference 203 ranks #12 of 56 floorstanding speakers at $5000. The Revel F206 ranks #17 at $2000, $3000 cheaper.
What the KEF Reference 203 gets right: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees). The catch: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums) - condition, driver matching, and component aging vary by unit.
What the Revel F206 offers: CEA2034 spinorama shows a pretty even on-axis response. Watch for: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz.
Buy the KEF Reference 203 if sound quality matters more than the price. Buy the Revel F206 if the price matters more than sound quality.

KEF Reference 203: $5000 Discontinued
Pros: An unusually accomplished 4-way design for its era: excellent on-axis linearity (within about +/-3dB), genuinely good directivity both horizontally (~55 degrees) and vertically (~40-50 degrees), and an estimated in-room response that closely matches what the reviewer actually heard. Distortion is excellent - under 1% harmonic above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good” - a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have.
Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums) - condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening. Discontinued.

Revel F206: $2000 used, Discontinued
Pros: CEA2034 spinorama shows a pretty even on-axis response. Predicted in-room response is excellent, with a smooth downward slope. Horizontal beamwidth of about ±65 degrees is wide, if a bit uneven. Distortion is very nice at 86dB SPL/1m, falling below the frequency range where human hearing is most sensitive, and stays excellent even at 96dB SPL/1m. Near-field measurements of the individual drivers show nice suppression of port and woofer resonances. Really amazing value for the performance.
Cons: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz. Vertical directivity means listening position needs to stay within the tweeter axis, though the reviewer notes there is some leeway. Minimum impedance dips to 3.3 ohms, calling for an amplifier comfortable with a demanding load. Discontinued.
