What's the consensus on meal planning?

I plan for the week. One, it helps with my grocery shopping. Two, I can prepack most of the things I take to work with me- I work 12 hour shifts, so on days that I work I ONLY eat there and take multiple small meals/snacks with me. Three, its pretty easy because when I go shopping for the week I buy enough of certain snacks to last through and I eat basically the same thing every day and then mix it up next time I go shopping. For me, this helps stop cravings and stops the unknown of what I am going to eat. I can plan out my meals to meet my macro and calorie goals. I just know what I have planned is what I will eat. I can see that might not work for everyone, though.
