Three questions you need to ask.

Where do you live?
If you have to commute where is the shortest?
Lastly, what is important to you? (upgrade, qol or career progression)

Psa has a flow with us air I think so when they start hiring next year you are guranteed a job there. No such gurantee at xjt. Plus xjt is about to merge with asa and from the way both groups are behaving I wouldn't want be there.
