Paul,
All the listed nav indicators work equally well with the IFD540. For me, it comes down to intuitiveness of the display.
In the test airplane I fly every day, I have the following nav indicators
KI-209a CDI
GI-106 CDI
KI-525 HSI
KI-229 RMI
Aspen PFD
I personally prefer "monkey bar" type indicators. For lateral and vertical deviation, the bars are perpendicular to each other and do not swing in a pendulum type movement - I find the pendulum variants to be sub-optimal from an intuitiveness perspective. I always have to think and interpret what I'm seeing whereas monkey bars are instantly informative to me.
Maybe you were hoping for non-Avidyne folks to chime in in their recommendations so sorry if I jumped in. I have 3000+ hours flying behind an HSI but I've found the CDIs and EFIS's of the world to be a better combo. I can't believe I'm going to say this next statement, but it's true for me - of the nav indicators I listed above, I prefer the GI-106.
Probably all just personal preference...
