Hand-drawing is enjoyable and fully customisable. It's also the most common reason a bullet journal habit tracker gets abandoned: at the end of a busy month, redrawing the whole grid is a chore, so it doesn't get done, and the habit quietly goes with it.
The middle path a lot of people land on is printing the grid and decorating it by hand. You keep the part that's fun and skip the part that's admin. Print it at the size of your notebook page and glue or tape it in.
It also means a missed month costs you nothing. You print a fresh sheet in seconds instead of facing an hour of setup you don't have time for.
