401(k) or Roth IRA

Hey everyone, currently making πŸ₯œ at Lockheed. Right now I am maxing out my Roth 401(k) match (chose Roth cause im expecting to be in higher tax bracket at retirement). I have more money to invest, should I continue dumping in employers Roth 401(k) beyond the match, or should I put it into my Vanguard Roth IRA? Thanks!!! TC: 88k YOE: <1
