Zephyr and RastaLabs for OSCP?

Has anybody done these? Is it a good idea to try these two for practice for the OSCP exam? Am done with the PWK course, and am doing HTB and PG boxes, around 3-4/day, but there aren't that many boxes for AD environments, am following Lain's list. So I wanted to give one of these two or both a shot. Are they similar in difficulty?

EDIT: also, are there any other prolabs that are AD environment. And any other AD environments out there, apart from the ones in Lain's list?
