I use all of the above.
On planes like simple electrics where everything is out in the open, z-bent steel ends, wrapped and CA'd to CF pushrods work fine.
Z-bends at the servo, clevis at the surface for others.
Keepers instead of z-bends. The wire is bent 90 degrees only
Wheel collars instead of keepers..
There is no one "best" way to do it.
