but what are the advantage of the discs with holes, slotted finsihes?
what makes you decide to spend way more on these discs?
The holes on drilled disks are supposed to help dissipate heat, with grooves there to help de-glaze pads during very hard use and allow any gasses that may be created to escape. All helping to increase brake performance.
For most people the main deciding factor on spending more money on them is looks.
