My experience with London Best is very limited (having owned just one), and as to self-openers, just a Purdey 16 a very gracious friend let us shoot at the gun club. Did not like it, but
perhaps just not used to so much resistance when working the barrels.
I have found,
to me, the most ergonomically friendly action to be my Manufrance Ideals: the human index finger is quite strong and agile, and cocking the gun upon pulling the "underlever" seems effortless, with the barrels dropping and then closing like they are gliding on glass.
My subjective experience, nothing more, and no comparison between London and St. Etienne expressed or implied.
