Read the physical copy or buy the E-book?

Hi, all! So, I’ve been using my recently acquired Kindle for a while now, and I’ve been loving the experience! I love it som much tot the point that I want to buy e-book versions of some physical books that I have not yet read.

I know that this seems petty, but I’d like to get your inputs. Should I just stick with my physical copies, or should I buy their e-book versions? Is this a case of a sunk-cost fallacy? Or am I contemplating something irresponsible? Lol.
