## What the models said for it

- "Buy one major survey (like Robert Half or Mercer) to ensure you are paying within the 25th–75th percentiles" (Qwen 3.7 Flash, Compensation benchmarkin)

- "For HR: Choose Mercer/Radford for legally defensible board reviews" (Gemini 3.5 Flash, Compensation benchmarkin)

## And against it

- "Avoid traditional surveys (Mercer/Radford: $10k+/year) unless scaling." (Grok 4.1 Fast, Compensation benchmarkin)
- "high-end, legacy enterprise surveys like Mercer, Radford (Aon), or Willis Towers Watson (WTW)—which can easily cost $20,000 to $40,000+ annually—are generally out of reach" (Gemini 3.5 Flash, Compensation benchmarkin)
- "legacy giants like Mercer, Radford (Korn Ferry), and WTW dominate the Fortune 500, they are often cost-prohibitive for mid-market firms" (Qwen 3.7 Flash, Compensation benchmarkin)
