Dual master looks really trick and is based on race style systems. The independent masters allow you to properly size each for the independent systems. It also allows you to screw it up. They have an adjustable balance bar to tune in the front rear bias. But if you don't set them up right this becomes a headache. The dual masters require fab work on your firewall. They are the choice of real racecars so if set up right they are probably the best.
Dual masters are an easy bolt on deal. Wilwood and others sell properly sized masters for your system that will bolt right in place on the firewall. Many OEM masters are available to work with upgraded brake parts and OEM parts are proven workhorses.
Vacuum assist, why? For autocross/open track manual brakes give you better modulation and feel with just slightly more pedal effort. If your motor isn't EFI and has a cam and other performance upgrades vacuum at low rpm probably doesn't exist.
If you want the ease of power brakes coupled with a performance car then maybe hydroboost but I'd still say just go manual, simple and effective manual brakes.
