Mamba Stack F405 MK2 vs Mamba Stack Basic F405 Mini MK4

Hi there,
I am looking to buy a flight controller for an autonomous drone and have come across two compatible flight controllers, the Mamba Stack F405 MK2 and the Mamba Stack Basic F405 Mini MK4. It’s my first time buying a flight controller and I was just wondering if anyone could recommend which might be better. I see they are both similarly priced so was wondering what the pro’s and con’s of one each one is.
