Having done both...
if you want to spend your 30's regretting your lost youth........ignore your doubts, remain a JW and gIve into the guilt and pressure from the Window cleaners above you in the org.....become a pioneer.
If you want to be happy and enjoy freedom of thought and expression, leave the JW's.
If you want to learn something about the world and become an expert in something, maybe even offer something back to mankind, then educate yourself at college. Education is a protection, it teaches you how to safely procure information. it will make the Watchtower and Awake look like nothing more than the dishonerable self advertising it really is.
I have pioneered and gone to bethel, I have also gone to university. I literally CAN'T BELIEVE how I used to live, when a JW. There is nothing of sufficient value in the whole world that would be tempting enough to get me to swap my life back.
