On the one hand, after selling my Patek annual calendar (I departed from it to fund my IWC MR), I am tempted to own a PP again.
On the other hand, I am suspicious of the hype surrounding this brand, which I do not like 100%.
I think you really have to look very carefully at what you are buying here. As far as I've learned, there are fantastic movements but also a lot of watches including movements that are overpaid.
The 5970 for sure has a quality of it’s own and belongs to the first category.
