Whichever you find most engaging to read.

Neither - get a library card to get both for free.

Hi there. Your post would be better asked in our Simple Questions thread. It helps us keep the main subreddit focused around broader discussion rather topics which only apply to an individual. Thank you!

Kindle is good for digital, regular screens are hard on your eyes. I prefer physical if you can get a nice print, otherwise paperback is just ok

i think that if you like the experience of reading physical books you can always stick to that format, but if you don’t care too much and you’d like to read without the difficulties that carrying a physical book brings, you should try digital books. And even if you decide to read digital books, you can always choose which books you would like to read in digital and which ones you think would be worth of the physical copy

That's a good point, thank you.
