No single best speaker here - they are built to different priorities, and the right one depends on your room, your sources and what you listen to.
| Area | Better | Why |
|---|
| Bass | A | SVS Prime Wireless Pro digs deeper - 42Hz against 50Hz. A subwoofer would even that out. |
| Built-in power | A | SVS Prime Wireless Pro has the bigger amplifier (200W vs 130W RMS). |
| Connections | A | SVS Prime Wireless Pro adds Wi-Fi, streaming and HDMI; Kanto TUK adds phono. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Expandability | depends | SVS Prime Wireless Pro: a sub output; Kanto TUK: a sub output. |
| Price | evenly matched | Much the same money ($899 vs $900 a pair). |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
SVS Prime Wireless Pro has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 50Hz anyway, so judge these on the other rows instead.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
