I reckon at the bottom of the pile would be the Swordfish with the HS-123 above it with the HE-51 above that simply because it was designed as a fighter even though it was soon obsolete. The Fury I would place above that as I understand it was quite an acrobatic aircraft for it's time.
Above that I'd think the P-26 then the I-16. The I-15 and the CR32 I understand were generally considered about equal during the Spanish civil war so would go in at the same point although there must be differences in how they flew. That leaves the Gladiator at the top as I understand it was considered about equal to the CR42 during WWII.
I'll admit that my knowledge of some of these aircraft is very basic and I'm not sure were to find the information I'm after so hopefully you kind people here will be able to help me.
