I thought since we are talking about which aircraft should be voted for inclusion into AH I would post some information about the delightful handling characteristic of this little fighter that served the Finnish Air Force so well over 60 years ago.
Here are couple of anecdotes about the handling qualities of the Brewster from the Francis Dean's famous book "America's hundred thousand":
The following comments are particularly interesting considering that they are from the U.S. Navy pilots who had been flying very maneuverable F3F biplane fighters before the Brewster.
Navy pilot: "When first produced the F2A-1 was an excellent aerobatic aircraft, a delight to fly."
Another Navy pilot (about the F2A-2 version, probably before some of the weight gaining modifications): "I think it would have matched the Zero (in maneuverability)."
Foreign quote about the regarding the 339 export version: "The Buffalo could almost match Zeke 22 for maneuverability."
The British commented: "The aircrfat was excellent for all acrobatics. It behaves with the ease of a Gloster Gladiator, and is just as simple to acrobat."
General comments about (during) maneuvering: "Elevators were very effective", "Ailerons were highly effective throughout the speed range" and "Rudder performance was good".
Comments from the finnish pilots are generally very similar to these.
So here is what I think it would be in AH:
It would be the slowest fighter in the game, with very similar turn rate and radius as the A6M2 with a nice roll rate (significantly faster than Hawk-75A according to finns). It would also have very good high speed handling. In general it would be easy and delightful to fly. It just can,t run or catch anything.
