SSBC Rear Disc Brake Conversion Kit difference?

I wonder if it will affect pedal feel? Wonder if the surface of the drums would be equal to or greater stoping force than the disks? Also you will give up some of your parking brake effectiveness as well. The drums are a perfect parking brake

Yeah not sure about pedal feel and how much more effective it would be. Biggest reason I was going switch to disc is so I can change to big bolt pattern wheels.
