Are Airmega cylinders worse that boxes? I cannot find definitive answers to this.
Honestly, I'm not sure if you'll really notice a difference in terms of performance and getting your air clean. My understanding is that the difference comes from potential longevity of the filters. Having a dedicated removable pre-filter and regular cleaning will prolong the life of the HEPA filter

2,720 ft³ space, 2 adults, 1 medium dog, UK = Coway 350?
Yep, should be adequate for the space. In the USA, Airmega 350 debuted just under a year ago. It seems to have good reviews so far. Keep in mind the Clean Air Delivery Rate (CADR) listed for it applies to the highest airflow speed/setting only. Lower settings have lower CADRs which reduces cleaning
