The verdict seems to be that if you were Norweigian flying against early Soviet pilots, it wasn't bad.
If you were a U.S. pilot flying a Buffalo, it was pretty much a dog that flew like a really nice sport plane, but wasn't any good for combat against decent adversaries in reasonable equipment.
Hi,
I think that there is likely more to it than that (assuming that you mean Finnish instead of Norwegian).
Specifically, if I am recalling correctly (iirc) the Finns recieved there Brewster fighters right at the end of the Winter War, and as such had a chance t familiarize themselves with the planes and work out some issues, partiularly with the engine piston rings (iirc) before the start of the Continuation War. In addition, as these planes were amoung the most modern aircraft that the Finns had in a reasonably large number, they were assigned to a squadron with experienced well-trained pilots.
Meanwhile, in the Far East, as I understand it, many of the pilots in the RAF and RAAf were fairly new (many straight from training) with little experience with these aircraft, and the ground crews were still working out many issues with the engines, weapons, and other systems, especially in the rainy/humid environment and lack of ground crew personnel may have greatly impacted the continued performance of the aircraft over time.
Also, at Midway, as I understand it, some of the pilots had just been transferred in to the squadron there and it is unlcear to me how familiar they were with either the F2A's or F4F's used there. In addition it does not appear that they had a chance to try and incorporate and lessons learned by the Navy from recent operations such as the Battle of the Coral Seas.
As such, Pilot experience, familiarity with the aircraft type and its characteristics, and ground support may have also played a significant role in the overall abilities of the Brewster variants in the different theatres that it operated in.
Added to this there are also issues with the level of experience of the opposition faced by the pilots flying the different variants of the Brewster aircraft in the different theatres of operations, with the early Soviet forces potentially not being as experienced while the Japanese in the Far East, potentially having some experience from the ongoing war between Japan and China, and the Japanese at Midway from the Kido Butai likely being very experienced, and high quality pilots.

PS. One last note that I think may sometimes get overlooked is that in regards to trying to use "boom and zoom" tactics as opposed to dogfighting an oppenent, its not always realized that the best speed for climbing for a given aircraft is often far from that aircraft's top speed at a given altitude. Specifically, I recall reading an account from a pilot in the Far East noting that while his plane was climbing at about 180mph, the Japanese were speeding past him at more than 300 mph.
As such, if a squadron does not have enough forwarning to make it to altitude before encountering their opposition they will likely be even more disadvantaged than you might otherwise think if you are just looking at the airplanes' rated top speed.
