List of recommended Comparisons

Of course, not all comparisons make sense: Why would you want to compare Strebe 1995 with Wagner VII? – Their distinctions are clearly obvious. On the other hand, there are projections which are very similar so you have to look twice to spot the differences.

So I put together a list of such pairs of projections.
Moreover, I’ve added a few pairings of projections that are not that much alike but, for one reasons or another, quite interesting to compare nonetheless.
