In the "best sentences I've read tonight" department, from J.B. Lightfoot's The Apostolic Fathers Part I: S. Clement of Rome. A Revised Text with Introductions, Notes, Dissertations and Translations (Volume I). Macmillan: London 1890.

On the whole this MS appears to give a good text. The shortcomings of the scribe are generally such that they can be easily corrected; for they arise from petty carelessness and ignorance, and not from perverse ingenuity. (p. 120)

Follow-up (2007-03-29): After discussing Alexandrinus' version of First Clement, Lightfoot moves on to the version recorded in the Constantinopolitan MS. On p. 123-124, he writes:

[Constantinopolitanus] is written with a fair amount of care throughout, so far as regards errors of transcription. In this respect it compares favourably with A, which constantly betrays evidence of great negligence on the part of the scribe. But, though far more free from mere clerical errors, yet in all points which vitally affect the trustworthiness of a MS, it must certainly yield the palm to the Alexandrian. The scribe of A may be careless, but he is guileless also. On the other hand the text of C shows manifest traces of critical revision, as will appear in the sequel.
