What the edition found
Same visibility, opposite verdict: only Reputation splits companies named as often
Rising Star and Bad Press sit in the same column, named at the edge: Presence 16 to 29 against 24. What separates them is Reputation, 80 to 94 against 0, either side of the line at 50. In Bad Press, Bathla Group was cautioned against more often than recommended in the answers that named it.
11 developers the engines recommend but rarely name
11 of the 17 companies on the Leaderboard are Cult Favourites: named in under 15 percent of answers, and recommended for their benefits in the answers that reach them. Listed by composite, they include Meriton (48), Goodman (47), and Coronation Property (46).
Further findings
Most of the Leaderboard needs to be found
Across the Leaderboard, the most room in the composite is Reputation for one; Influence for two; Presence for 14. The most room is the factor whose weight, times the points it sits short of a full score, is largest: the most composite still to gain.
Who could move by the next edition
On the Leaderboard, these companies' ranges reach a line, so the sample cannot place them firmly on their side of it. Presence, against the line at 30: Lendlease (26 to 32) and Stockland (24 to 30). Presence, against the line at 15: Billbergia (13 to 18).
Edition 1 read 830 answers from five AI engines (ChatGPT, Claude, Copilot, Gemini, and Perplexity) to 166 buyer questions. The engines named 17 companies. The 17 named most are on the Leaderboard, each scored on all five factors.
