>In y'alls' experience, is it faster to crush and strain a super as opposed to removing the cappings and extracting in a 2-frame junior bench extractor (which I was lucky enough to have a brother give to me)?

Yes it's faster to crush and strain. But you'll get more honey next year if you have drawn comb... if you have more honey than you need anyway, it probably doesn't matter. If you need more wax, then crush and strain would be better.
