Prayers don’t actually work in reality, unless one relies on lucky coincidences and pure chance. Diligent research, on the other hand, coupled with the scientific method actually does work more often than not.
To the OP. I would urge you to ignore anecdotes. You’ll hear horror stories from both camps. They are meaningless. Do some research. If you still think it viable to spend the extra on a MAC then go with that. Other wise build a powerful PC with quality components and have enough left over to buy a good UAD-2 system, or similar.
