Short answer: the JBL HDI-3600, if you are buying new. The Revel F208 ranks higher than it (#16 vs #31 of 74 floorstanding speakers, 4.5/5 vs 4.3/5) but is discontinued, so only consider it used; the JBL HDI-3600 is still sold new at $3,800.
Buy the JBL HDI-3600 new; the Revel F208 is no longer sold new, so it only makes sense as a used find.

Revel F208: $4,800 per pair used Discontinued eBay
Newer model: the Revel F228Be, ranked lower, rated 4.5/5.
Pros: CEA2034 spinorama shows a fairly even on-axis response with sensitivity matching spec at ~87-88dB. Predicted in-room response is a smooth, textbook-quality downward slope that should translate well to most rooms without correction. Early reflections sum so cleanly with the direct sound that side-wall absorption isn’t recommended: it would work against the speaker’s naturally well-integrated off-axis behavior. Distortion stays below 0.5% from 100Hz up at 96dB/1m, with all distortion components falling below audible threshold above 200Hz. Very wide horizontal directivity of about ±75 degrees. Measured performance was judged very close to Revel’s own flagship Salon2, and Revel’s speakers (including this one) are developed using Harman’s double-blind listening test methodology. Preference score of 7.4 (7.7 with a subwoofer added). Measured bass extension of 47Hz (-3dB), with a measured sensitivity of 88.2dB.
Cons: Some directivity error and tweeter-response ripple right at the 2.2kHz crossover point. A notable on-axis dip at about 4kHz, attributed to probable cabinet diffraction. Cumulative spectral decay (waterfall) shows an unexplained resonance around 4-5kHz that the reviewer couldn’t pin down a clear cause for. Vertical directivity shows narrowband interference nulls just above and below the tweeter axis (roughly 2-3kHz), typical of a non-coaxial tower with vertically separated drivers, so listening height matters more than it would with a coincident design. Minimum impedance dips to 3.4 ohms, calling for a robust, high-current amplifier. Distortion climbs substantially below about 80-100Hz (up to ~5% in the deep bass) when driven hard, an excursion-limited trade-off typical of towers at high output. Isolating the woofers alone shows their usable range ending around 500-700Hz at the crossover, with somewhat elevated (though still low in absolute terms) 2nd/3rd harmonic distortion in the 100-300Hz region. Discontinued.

JBL HDI-3600: $3800 per pair Audio Advice eBay
Pros: CEA2034 spinorama shows a fairly even on-axis response and flat overall frequency response, with high 90dB sensitivity and very low distortion through the midrange. Triple 6.5” Advanced Aluminum Matrix woofers and a 1” compression driver in JBL’s HDI waveguide. Measured bass extension of 78Hz (-3dB), with a measured sensitivity of 89.5dB.
Cons: A wide shelving-down above 2kHz affects the in-room response, and vertical dispersion is a bigger issue than horizontal: the reviewer noted the dip is wider here than on the smaller HDI-1600, making it more audible. Narrow vertical sweet spot means careful listener-height positioning matters more than usual.
