As per our standards, it could be wrong.
The surveyor may not be credible, or not be accredited.
Nope, they listed their criteria:
Then we judged cities in four areas, using a one-to-10 scoring scale for each category:
1. Getting around: Quality of public transportation, affordability and availability of cabs.
2. Value: Bargain opportunities, such as sale seasons and average prices.
3. Variety: Number of available brands, range of shopping categories, quantity of upscale shops, department stores, boutique and vintage retailers and market stalls.
4. Experience: City beauty, quality of window displays and shop décor, friendliness and competence of clerks and service staff, dining and accommodation options.
I agree SG will get low score in the above categories....
