I found their prose to be quite good. It's sad that it seems long-winded to modern readers. These letters are not long. Maybe attention spans are too short.

Some of the "verbosity" seems to arise from their apparently mutual concern to preserve their relationship by delivering criticism of ideas or behaviors without attacking the person. We could certainly use more of this style of communication today, but all it earns now is a "TL;DR" at the beginning or the end.
