New job has 403b and I have a 401k. What?

I have a 401k with Vanguard that’s invested in target date 2045 fund.

I’m starting a new job that has 403b.
Should I keep the 401k and continue my auto-deposit of $50/week? It’s on auto pilot and I rarely check up on it.

I will take advantage of employer match on the 403b.

Should I combine them?
