Great is an easy word to overuse, in part because it covers so much ground. It can mean important, vast, or even skillful. But when you're looking for a more lively and emphatic term to describe something as excellent or first-rate, wonderful is a nice option. Wonderful, in its most literal sense, means "full of wonder." It connotes a sense of astonishment, surprise, or admiration, which is perhaps why it's so frequently followed by an exclamation mark! But be careful, because just like great, wonderful can be used in an ironic sense to mean just the opposite, as in, "After arriving late to a meeting and seeing his boss look at him angrily, he sighed to himself, 'wonderful.'"
