They are both fine competitors in powered desktop speakers. They have their own built-in amps = footprint space savers .
Your ultimate choice depends on a very subjective evaluation of :
(1) Connectivity options, especially Blutooth and dual optical inputs, direct phono Turntable preamp, and a direct subwoofer out
(2) alternative speaker finish aesthetics (if important )
(3) every speaker has its own bespoke unique sonic signature ...
(4) Options: including footprint and size and power ( with matched price points). The KANTOS are available in three models.... the “2”, “4” and “6”
https://www.audioadvice.com/content/kanto-yu2-yu4-yu6-speaker-comparison/I demoed the AE and KANTO both in a bake-off for my “C” system..... the KANTOs won out in my desktop system.
The KANTOS also come in various funky colour gloss finish options that helped the WAF option when I drag them outside as BBQ self-powered stand-alone wireless on-the-deck-party performers through an iPhone / iPad digital source via Bluetooth OR direct RCA input via TT.
The KANTO YU6 has with a formidable and beefy Class D amplifier pumping out 200W peak power, (100W RMS)
Because speakers are subjective, my guess is that is a likely a close tie overall in any general personal fave opinion desktop-use bake-off.
I will add that my inclusion of a (under-table at my desk) direct output via cable subwoofer (KANTO has their own matched set small one but any one will do) was a BIG final audio performance step-up overall; that facilitated a more pleasing overall audio improvement especially at both
(a) lower volumes in a nearfield desktop listening arena, and,
(b) louder volumes as required for outside party use.
