Which should you buy?
The 7770i is the clear pick on raw spec strength, leading by 17.6 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
Pick the 7770i if you care most about coverage and cadr. The biggest gaps in its favor are coverage, cadr, min noise.
The Core 600S similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable true hepa h13+, activated carbon, so those specs don't separate the two — focus on the differences below.
