Best and worst are subjective terms. I've read many acclaimed book by famous authors with 5 star reviews up the wazoo on Amazon, and often thought, 'Meh, can't the author come up with something original?' and, 'I guess he was pantsing and couldn't figure out the ending and had to come up with the old, and then a miracle happened, to finish the book.' Obviously others loved those books, but I sure didn't.
I suggest reading a lot across several genres. You'll probably be drawn to some, and repelled by others.
A friend likes to say that we can learn something from anyone, but the most common lesson is patience.
