Even if it could be done, comparing "one lesson" would be a completely useless exercise. There is no substitute for actually examining and comparing books side by side, as I have done. For example, if you will actually compare the Euclidean Geometry books that I discussed at the link below, you will find that:
1. My high school textbook contains a 10page introduction to basic notions and postulates. The next 11 pages cover various constructions and axioms. Congruent triangles and proofs start on page 29.
2. The JurgensenDolciani book forced students to plow through a 190page quagmire before congruent triangles come up.
The power of the written word is eternal, and no amount of sophistryand no amount of flimflam on your partcan deny the fact that the Dolciani series demolished the traditional college preparatory mathematics curriculum in the U.S.
