Do you need to go outside to compose a melody? How about capture some drone footage? 
Yes, there are differences. And yes, at several distinct points over the years different markets have seen different historic queue times… When VideoHive was over 100 days, AudioJungle was not.
As many a seasoned AJ author could tell you, queue times rise and fall more than once very year. When the AJ queue was at 35 days, 18 felt fast… But when it had been at 3 days, 7 felt slow… and the rightfully puzzled questions of newer authors on the forums always followed suit.
The desire for consistency is certainly understood, but this certain tendency of yearly ups and downs will always mean that there may be significant swings in certain periods, in the spring and in the fall.
Thanks for your understanding, and for always staying curious
