How can I test how well a choke balun is performing? I know how to test a
transformer balun, but am cluless as how I can compare several different
choke balun approaches.

I dont have the skills nor knowledge to tell you how to test the choke
balun. I do have some experience with testing of my home made choke
baluns.
I made connection to the shield of the coax that is surrounded by the
"choke balun", and measured the impedance across it. My reasoning was that
the major objective of the balun was to present a high impedance to current
along the outside of the coax.
It occurres to me that my reasoning might be invalid, since it seems too
obvious, and you already know the "impedance" test isnt adequet.
