If so, what was your impression?

Not yet. But I have flown an LNAV with advisory vertical guidance. The
needles were extremely stable -- more so than an ILS with my equipment.
Pretty easy to fly.

Yes, the approaches are a pleasure to fly, but the step change in course
width can cause a coupled approach to give a small disturbance, for me.
If the needle isn't exactly centered at the point of switching,
my autopilot hunts for a few moments, until it stabilizes again.
It's a small amount, and not an operational problem, but it makes the GPS
approaches slightly less smooth than an ILS, which doesn't have that bump.
My autopilot is a Collins AP-107.
Who sees any similar effect with other autopilots?
