For me I find that physical books immerse me more in the story if I'm actually sitting down to read (not to mention I remember more details), but audiobooks are great if you're in the middle of something such as cleaning or driving.

My normal go-to is physical books when you're waiting or have free time, audiobooks if you're driving or doing chores (yay Bluetooth speaker).

It also depends on the narrator they pick for the audiobook.

Example, True Grit as read by Donna Tartt was a fantastic audiobook because both she and the main character are from the South (U.S.), and her reading combined with Charles Portis' writing was so natural-sounding that it literally sounded like I was listening to a firsthand historical account instead of some fictional retelling (the book is written in first-person).

My suggestion, play around a bit and see what you like best.

My cousin has ADHD so audiobooks works better for him. I prefer physical books because once my brain gets into it after 10 or 20 pages, I can't put the book down.

Whatever works for you.
