In an analog synth the square wave has some distortion to it: the rise is not instantaneous and there is some overshoot of the peak too. Over the years this was minimized by using high slew rate amp circuits and the like so an old Moog pulse wave is less ideal in shape than a new one.
For a digital square wave you would want to use band limiting to avoid alias artifacts which are quite severe for a square or sawtooth wave. As the frequency goes higher both of those waves will begin to look more like sine waves as the partials are filtered out. Pretty much every commercial digital synth and plugin uses anti-aliased waveforms.
However when using this as a LOW frequency oscillator, I would simply ignore the literature on bandlimiting and go with a pure digital aliased wave full force! :)
