I think you're asking about 2 components. The electronic distributor is an iprovement over points. Points will slowly wear, and change your dwell over time. Electronic stays consistant through it's service life. But, the electronic module can be sensative to voltage spikes, and can easily burn out.

The "Magic Box" behind the glove compartment can perform a number of functions. But, for your type of driving it really doesn't do anything. You could eliminate that component and not see any difference at all.
