Short answer: both are discontinued, so this only matters if you are buying used. Used, the Revel F206 is the better pick: it ranks #30 of 226 floorstanding speakers by sound quality (rated 4.5/5), against #88 (rated 4.2/5) for the Infinity Primus 360. If you want one new, the Revel F226Be replaces the Revel F206 and is rated 4.6/5 at $8,469.90.
The Revel F206 is the more accurate option. CEA2034 spinorama shows a pretty even on-axis response. Its measured preference score, a predictor of how neutral it sounds, is 5.51 against 4.97 for the Infinity Primus 360. Watch for: Some directivity error and a small peak around 4.5kHz show up alongside the directivity error around 3kHz.
The Infinity Primus 360 is the deeper-bass pick. Its bass reaches about 53Hz before falling 3dB, against 60Hz for the Revel F206. Watch for: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average.
Buy the Revel F206 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Revel F226Be, which replaces the Revel F206.

Revel F206: $2,000 per pair used Discontinued eBay
Newer model: the Revel F226Be, ranked higher, rated 4.6/5. See every Revel Performa generation.
Same family: the Revel M105 (smaller bookshelf, rated 4.2/5), the Revel M106 (larger bookshelf, rated 4.6/5), the Revel F208 (larger floorstanding, ranked higher, rated 4.5/5), the Revel Performa3 C205 (smaller center, rated 4.1/5) and the Revel Performa3 C208 (larger center, rated 4/5).
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. Measured bass extension of 60Hz (-3dB), with a measured sensitivity of 87dB.
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.

Infinity Primus 360: $650 per pair Discontinued eBay
Same family: the Infinity Primus 150 (bookshelf, rated 3.4/5).
Pros: A three-way tower from 2005 (two 6.5” mid-woofers, a 4” mid-range, and a 0.75” dome tweeter, 8 ohms nominal) that holds up remarkably well by modern measurement standards: on-axis linearity is within about ±2dB, and the listening window stays consistent out to roughly ±30° horizontal and ±10° vertical off the mid-range axis. Horizontal directivity is well controlled out to about ±75° before tonality starts to drift, meaning the reflected sound in a room stays close in character to the direct sound: a speaker that takes EQ well without fighting itself. Harmonic distortion measures low at both 86dB and 96dB, and multitone distortion stays under the reviewer’s 3% threshold. Silky, smooth midrange with a rich lower-midrange/upper-bass character. No mechanical issues or surround degradation found in a 20-year-old pair, and a second unit measured within about 1-1.5dB of the first, suggesting good long-term consistency for the design. Measured bass extension of 53Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: Manufacturer-spec sensitivity of 93dB runs about 3-4dB optimistic versus the measured 89.4dB average. Bass output drops off fairly quickly below about 50Hz in-room (F3 53Hz, F10 37Hz), so a subwoofer is needed for real low-end extension. Resonances show up around 170Hz, 220Hz, and 350Hz. On-axis, the lower treble can sound a bit bright or sibilant when the speaker is aimed directly at the listener; toeing out about 10-15° (rather than the more extreme 30°) gave the best balance, and some sidewall acoustic absorption further tamed a 4-5kHz peak. Placed close to the rear wall, bass gets boomy: pulling the speakers out about a foot resolves most of it, with roughly 1.5 feet from the wall as a good compromise between bass character and typical room aesthetics. Straying beyond about 25° above or below the mid-range axis introduces audible suckout. No longer in production, so it’s a used/secondhand purchase only.
