I just installed the new enhanced AX MCs and used them last night. The difference in combat effectiveness against Thargoid scouts was very noticeable for me.
Full disclosure: Prior to Update 14, my AX activity and experience was very limited... it was probably <5% of my activities.
Hopefully the AX scanner gets a serious buff to range and/or scan time. Prior to update 14, the AX scanner was a challenge to effectively operate, given the speed and agility of the interceptors and their ability to move outside the scanner range. Now, with them taking an instantly hostile posture, it's almost impossible to use it without receiving an enormous amount of damage.
