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.

|---|
| Bass | B | Q Acoustics Q Active 200 digs deeper - 46Hz against 64Hz. |
| Built-in power | A | PSB Alpha iQ has the bigger amplifier (180W vs 100W RMS). |
| Connections | B | Q Acoustics Q Active 200 adds Wi-Fi. |

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?
Q Acoustics Q Active 200 is ahead, but only on 1 of the measured areas, and it costs about 40% more. That is a lot of money for a narrow margin on paper - PSB Alpha iQ looks like the sensible buy unless something else about the Q Acoustics Q Active 200 appeals to you. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 64Hz anyway, which makes the cheaper PSB Alpha iQ much easier to justify. In a large or open-plan room, Q Acoustics Q Active 200 has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, PSB Alpha iQ is the easier speaker to get right.
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.
