I read a mix of ebooks and physical books. Usually the choice is determined by the type of book. For example, usually more genre fiction gets an ebook, whereas more so called "literary fiction" gets a physical copy.

For example I've picked up House of Leaves at a local independent bookstore, along with the Molloy books by Beckett and the Norton Annotated Moby Dick. I don't think house of leaves would work at all as an ebook and heavily annotated items I prefer a physical copy.

Alas I am running out of bookshelf space so I have to be much more selective these days. As for finding books, it's usually word of mouth or on storygraph. I also follow the book youtube Leaf by Leaf whom I can thoroughly recommend.

The ebooks I prefer on eink devices, for portability I have a Kobo and for notetaking or needing a bigger screen I have a supernote A5X
