Sounds like the coil or a bad ground somewhere.
The sensor is basically an ON/OFF switch. If the sensor fails, no spark at all. It can't 'half fail'. . Very easy to swap the coils across the engines, so that's definitely what I'd do first. It could be the ignition amplifier (the switch box), but unlikely as they usually work or not work. Poor spark can also be a bad rotor (which you have replaced. BTW, it's not a bad design. The rotor is loctited in to reduce vertical float. They very very rarely fail). Bad contacts on the distributor cap (also replaced) or a bad wire (did you replace the coil -> cap lead?)...
