I've got 2 cars that came with them and I wish they didn't.

Can confirm this. I tried slotted and drilled before on my garage queen for looks. If you try to use these things for your daily driver(which I also did), it's not a good idea unless you live in California or similar places.
The slotted rotors are ok but it'll make dust and eat pads faster. The cross drilled rotors tend to crack and cause banding since most of the ones you see are cheaply made.

Both the slots and drill holes will have permanent rust if you don't paint it with high temp paint before installing. Sometimes, these rotors will actually worsen your braking power.
I highly recommend not trying this if you live in the North East because it's more problems than it's worth. Unless, of course, it's your garage queen.
Please do not take these rotors to the track either. It's not safe.
The real stuff is very expensive but you probably already know this. The best mod, in the F10, to stop faster is replacing the oem runflats.
