Hardcover? Or paperback?
Illustrations? Or just text?
First editions? Or you don’t care?
Signed by the author? Or not?
In general I definitely prefer hardcover books. They are more durable, and this is an issue to me because I keep all but the most unworthy books. It is hard to read paperback books without bending or creasing the cover in some way, and I like my books to stay looking nice, and unread. There are occasions when paperbacks are preferable, such as on the beach, while travelling, or while nursing a baby; when there is a danger of the book getting destroyed, or when I only have one hand available, ore when I have limited space.
I love illustrated books. It is really to bad that, other than children's pictures books, so few books have any illustrations anymore. I have some books of Charles Dickens' with illustrations, and find the reading that much more enjoyable.
As for first editions, really not an issue for me at this point. I don't collect books as collectors items. Though I do like to have nice books, for me they are about functionality. At some point in the future if I have the kind of money to be able to spend it on books that I will not read, it is a possibility I could begin to collect.
To have a book personalized by the author would always be a plus. I currently only have a couple of signed books, but would welcome more.
