What supermarket is easier to access by car?

My friend is coming down with her car so it’s an opportunity to do a big shopping load before our road trip to see friends in Canada. We are debating between Trader Joes for the pricing or Costco for the bulk.

I’m near Myrtle-Wyckoff (i know food baazar is there but it’s a little pricey for what i need) and would be fine with either option. It’s really just about convenience.

Sorry if this is a weird question lol. I have only taken the subway to either. Thanks!
