I rarely have trouble finishing a book, so I can't advise you. I do know that IT scared the bejeepers out of me, but I scare easily, so that's not much of a barometer for you.

While I agree that The Stand was a superior read, I have a soft spot for the characters of IT and how brave they were, brandishing their innocence as a weapon. The love these characters develop for one another (most were strangers at the beginning of the book) was wonderfully portrayed.
