Both jobs get you on set where you have the opportunity to create relationships.
What's important is to have a "passion story" for both. The reason is if someone who knows you as an actor sees you on set as a PA and asks you about it, you can tell them your passion story. An example may be that your long term goal is to be an actor with a production company so during your pursuit of acting work, you're familiarizing yourself with work on the set.
The key element is believing in what you're doing, so should anybody tell you that you can't do both, your confidence in your decision will prove that you can.
