I have mainly experience with shoes from Carmina, Edward Green, C&J, Allen Edmonds, Ed Meier and looked at plenty of real life examples from John Lobb Paris, Alden, Church's. For other makers my knowledge consists mainly of photos, which may or may not give a good impression of the real shoe.
My current favorite is the Simpson last of Carmina. I like soft chiseled, slightly squared-off and slim-waisted lasts and the Simpson is closest to my ideal.
The C&J 348/358 comes 2nd for me. The C&J 337 is not slim enough. I love Edward Green shoes based on finish and construction, but the 888 and 890 look a bit chunky at the toe; the 808 is nice, but seems to be used less and less. Allen Edmonds may have many merits - beauty of lasts is not among them IMHO.
