Electronic systems will deliver a better, stronger spark regardless over a coil/breaker system BUT certainly my Vit is electronic. It looks standard right up till you strip the dizzy. Theres an ECU of sorts on the vit buried behind the speaker on the drivers side, dont know if this is true of the sammy.
Might be worth refurbing the whole system before you spend loads of money on something else. New plugs, leads cap, rotor and possibly coil. Made a world of difference to mine.
Audi has an aftermarket Luminition ECU and it never misses a beat, never had the OEM unit so I cant compare.
