I don't disagree with you at all. It is a sailors preference and each rig has an advantage. I've sailed on all except a squarerigged ship and have chosen a cutter
for simplicity and performance. If I were to choose another divided plan it would be a bermudan yawl because to me performance to windward matters. If windward performance doesn't matter to you as much then a ketch
or schooner is a good choice.
I, again, will say that the excerpts in rating efficiency are stating overall efficiency, not just windward efficiency which is what I'm after.
