Share of voice, top ten houses

What the first reading shows
20 houses, out of about 80
Across 12 answers, the engines named only 20 independent houses. The other 60 were never mentioned.
One house nearly everywhere
House A was named in 9 of 12 answers: every answer from three engines, in all three markets.
The city changes the answer
A house recommended for Switzerland can vanish when the family names a city. House F was named first for Switzerland by two engines, and by none for its own city.
Engines disagree
Perplexity never named House A, the house the three other engines cite most. Which engine a family uses decides who they hear about.
