Short answer: the Polk Signature Elite ES50. Both are rated 3.8/5 for sound quality (#156 and #154 of 226 floorstanding speakers), and the Polk Signature Elite ES50 costs $588 against $1,048.50 for the Aperion Audio Novus N5T, so with nothing between them on sound quality, price settles it.
What the Aperion Audio Novus N5T does well: A compact direct-sale tower with dual 5.25-inch aramid-fiber woofers, a silk-dome tweeter, free shipping and a 30-day home trial. Watch for: The -0.31dB-per-octave response tilt makes it moderately warm/dark, while on-axis smoothness of 0.267 is merely average.
The case for the Polk Signature Elite ES50: Slim compact floorstanding tower in the Signature Elite series featuring dual 5.25-inch mica-reinforced woofers and a 1-inch Terylene high-res dome tweeter. The catch: Rating estimated based on acoustic specifications and measured Signature Elite siblings (Polk Signature Elite ES15, Polk Signature Elite ES20, Polk Signature Elite ES60).
Buy the Polk Signature Elite ES50. Both are rated the same for sound quality, and it costs $460.50 less than the Aperion Audio Novus N5T.
About the ratings: the Polk Signature Elite ES50’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.6 to 4.0, so this verdict could change once it is measured.

Polk Signature Elite ES50: $588 per pair Passive Estimated Amazon eBay
Same family: the Polk Signature Elite ES10 (smallest bookshelf, estimated 3.1/5), the Polk Signature Elite ES15 (bookshelf, rated 3.5/5), the Polk Signature Elite ES20 (largest bookshelf, rated 3.7/5), the Polk Signature Elite ES55 (larger floorstanding, ranked higher, estimated 4/5), the Polk Signature Elite ES60 (larger floorstanding, ranked lower, rated 3.4/5), the Polk Audio Signature Elite ES30 (smaller center, estimated 3.5/5), the Polk Audio Signature Elite ES35 (larger center, estimated 3.4/5), the Polk Audio Signature Elite ES8 Subwoofer (smallest subwoofer, estimated 3.2/5), the Polk Audio Signature Elite ES10 Subwoofer (subwoofer, estimated 3.7/5) and the Polk Audio Signature Elite ES12 Subwoofer (largest subwoofer, estimated 3.8/5). See every Polk Signature generation.
Pros: Slim compact floorstanding tower in the Signature Elite series featuring dual 5.25-inch mica-reinforced woofers and a 1-inch Terylene high-res dome tweeter. Down-firing patented Power Port technology enhances laminar bass airflow and minimizes turbulent port noise, delivering clean extension down into the 40Hz range. Inherits the linear listening window and controlled dispersion demonstrated in Klippel NFS tests of the Polk Signature Elite ES15 and Polk Signature Elite ES60.
Cons: Rating estimated based on acoustic specifications and measured Signature Elite siblings (Polk Signature Elite ES15, Polk Signature Elite ES20, Polk Signature Elite ES60). Dual 5.25-inch drivers provide less low-frequency displacement and punch than the larger Polk Signature Elite ES55 and Polk Signature Elite ES60 towers.
