Audio-Technica ATH-PRO5MK3 vs ATH-M40X

Hello everyone!
I couldn’t find any reliable info on Pro5Mk3’s or direct comparisons with M40X. I’ve tried the ATH-M40X and they’re great, but I’d like to compare them to Pro5Mk3, since they’ve got my attention. They’re about the same price, but the Pro5Mk3’s are out of stock in my region (as 40’s were for a few months), so I’d like to know if they’re even worth waiting for.
Thank you.
