Short answer: the KEF Reference 3 Meta, if you are buying new. The KEF Reference 203 ranks higher than the Polk T50 (#17 vs #126 of 188 floorstanding speakers) but is discontinued; its replacement, the KEF Reference 3 Meta, is rated 4.6/5 at $15,999.98 and is still sold new.
The case for the Polk T50: Pretty deep bass for the price. The catch: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up.
The KEF Reference 203 is the more accurate choice. Its measured preference score, a predictor of how neutral it sounds, is 5.83 against 4.14 for the Polk T50. 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, so audition before buying if at all possible.
Buy the KEF Reference 3 Meta, the replacement for the discontinued KEF Reference 203; it is rated higher for sound quality than the Polk T50.

The Two Speakers In Full
Polk T50: $498 per pair Amazon eBay
Same family: the Polk T15 (bookshelf, rated 1.9/5).
Pros: Pretty deep bass for the price. Distortion at 86dB SPL/1m is reasonably controlled outside a narrow spike around 250Hz. The reviewer notes performance is “not too bad for a budget speaker” once the two main tonal issues are addressed with EQ. Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 86.3dB.
Cons: 5dB peak at 1kHz, 4dB bright top end from 11kHz on up. Just okay vertical off axis. Impedance and phase show several resonances between 200Hz-1kHz, with a minimum impedance of 4.2 ohms. Distortion rises substantially at 96dB SPL/1m across the midrange, with repeated peaks between 100Hz-2kHz.

KEF Reference 203: $5,000 per pair Discontinued eBay
Newer model: the KEF Reference 3 Meta, ranked lower, rated 4.6/5.
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. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.
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.
