I think going to power brakes will make a bigger difference in feel than going to manual discs which may give no additional difference in feel but might be beneficial if you're tracking the car and/or doing repeated 60-0s for some reason. I think people forget the main appeal of disc and/or larger brakes is more repeatable stopping rather than simply more stopping power. Will 13" brakes and six piston calipers with pads that have immense surface area bring your car to a stop faster than 1965 Mustang drums? Certainly. Will the puny disc brakes of the era bring your car to a stop faster than drum brakes? Maybe. Will they do it faster the 3rd or 4th time in a row? Absolutely.
I daily drive a Toyota Camry. I actually like my Mustang because the driving experience is more spartan, four wheel manual drums being part of that.
