If you got it apart put it in.

You might have done too much work as my logic would be replace everything when doing the evaporator, other wise replace actuators till the one inside the case is bad. If the case comes apart might as well do all the elements.

As for which to use I agree the copper ones are tooo crude. The ACM with expansion valve and boot is the way to go.
