I have both blocks, I much prefer the EVO. I actually decided to use the Pro when I put my water setup back together, but I felt bad with no EVO, a sort of guilty 'bad' feeling, and it disapeared when I replaced the pro with the trustly old EVO.
When I was browsing reviews, a lot of people yapp about 'top performance', but if my setup is not as good as yours and I'm only 2-3° off, I don't see how the other setup is billed as the absolute best. If it was 10°C off, sure, but anything less than 5 isn't enough to warrant a change for me.
