We can try some kind of breakdown.
In the fighter branch, RAF is a close second by 1941 contender, with LW having a good LR fighter all the time.
In SE bombers, Ju-87 and Il-2 are at top.
In twin-engined bomber class, Ju-88 leads, but RAF evens things via better torpedo bombers here (Beaufort, Hampden); Beaufighter features rockets already IIRC. USA has some strong contenders in A-20 B-25, making all 3 AF pretty even.
RAF has the edge in really heavy bombers, USA second with early B-17s.
In MP class things are pretty even - RAF has the edge due to electronics greater emphasis on this key issue.
Transports are pretty even.
Radars are good, after what RAF has at disposal, and much later.
LW has top pilots here; those are hampered by Goerings Hitlers decisions, though. The other main thing is that Germany is outproduced, and US production is bulking up the numbers of planes RAF VVS have at disposal.
Any advantage Luftwaffe held in 1939 is pretty much thinned out by 1941.
