I recently used Huntsman. The results were rather drapey- not at all what I expected from their reputation. This remains the airiest of all the bespoke suits I have all of which are from a single tailor in Bangkok who, I have used for 10years.
However the finished product was very nice indeed in its own way. The process was very smooth. However it was a bit more than 2000. Overall I think my Bangkok guy does a better job at a much more modest budget
