A generation apart: Jamo S 801 PM is the newer design, against a 2011 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.

depends neither is better in the abstract - it turns on your room, placement 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 76Hz anyway, which makes the cheaper Jamo S 801 PM much easier to justify. In a large or open-plan room, Audioengine A5+N has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Jamo S 801 PM 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.
