# 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.
