Over the years I have tried many different Itailans (different sources), Russians, Carnolian, Midnites, Starlines. To be perfectly honest with the small sample size that most backyard beekeepers have doesn't lead to any real indication of trait differentiation. There are just to many other variables within breeders that affect results.
Just within Italians I have had many different experiences from very hot ones to extremely gentle. Massive burr comb to minimal burr comb. Good producers, bad producers. So it is hard to quantify any other breed based on just a few of each type.
