It's tough, it has been a while since I tested them together. From memory, I would say the Kunos car (and update) is a bit more stable but also more sluggish to react. The bm version, as I said, it sometimes a bit twitchy when you would expect an AMG to be very stable. Both of them are too quick in a straight line (+- 25kmh) and the dash on the bm version suffers from the same thing the rF2 AMG GT3 does with an odd-looking dash. I have also seen the AGU update to mess with screenshots with the car itself being very low res (when using the CM/CSP upscale feature). Both have their strengths and weaknesses but both are serviceable. I will have a go with the Kunos updated version in the next few days, but I would say: maybe install them both and give them a shot, they are both free.
