Short answer: the PSB Alpha T20. It ranks #142 of 226 floorstanding speakers by sound quality, rated 3.9/5, at $1,099; the MartinLogan Motion F10 ranks #157, rated 3.8/5, and costs $2,239.98, so there is not much of a tradeoff to weigh.
The case for the PSB Alpha T20: Dual 5.25-inch floorstanding loudspeaker voiced by Paul Barton featuring textured polypropylene woofers and a 0.75-inch black anodized aluminum dome tweeter with front waveguide. Watch for: Rating estimated based on Alpha series sibling testing.
The case for the MartinLogan Motion F10: 3-way floorstander with dedicated 5.5-inch fiberglass midrange and twin 5.5-inch aluminum woofers relieving the Gen2 Folded Motion tweeter of low-end duties. The tradeoff: Frequency response carries an upward treble tilt consistent with the Motion line voicing, resulting in a bright balance that can sound analytical in reflective rooms.
Buy the PSB Alpha T20. It is rated higher for sound quality than the MartinLogan Motion F10 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: PSB Alpha T20 3.7 to 4.1; MartinLogan Motion F10 3.6 to 4.0). Treat this verdict as provisional.

MartinLogan Motion F10: $2,239.98 per pair Estimated Best Buy eBay
Same family: the MartinLogan Motion B10 (bookshelf, rated 3.6/5), the MartinLogan Motion F20 (larger floorstanding, ranked higher, estimated 3.9/5), the MartinLogan Motion C10 (center, estimated 3.7/5) and the MartinLogan Motion MP10 (surround, estimated 3.5/5).
Pros: 3-way floorstander with dedicated 5.5-inch fiberglass midrange and twin 5.5-inch aluminum woofers relieving the Gen2 Folded Motion tweeter of low-end duties. Down-firing twin ports provide smooth low-frequency room coupling down to 38Hz.
Cons: Frequency response carries an upward treble tilt consistent with the Motion line voicing, resulting in a bright balance that can sound analytical in reflective rooms. 4-ohm nominal impedance requires stable amplification.
