As a cortisol controller, which would be better used in PCT? Or could they be combined and still be effective?

Reduce XT is probably better for cortisol control specifically, but the two can be combined for an additive effect, since they operate on different pathways with the release of the new LX.

Correct. I'm more comfortable recommending Reduce XT from a health standpoint since I'm not sure of the degree to which the new LX compound will affect mineralcorticoid receptors.
