'unglaublich' and 'verblüffend' both describe something that is hard to believe. But 'unglaublich' is broader: it can mean something very great, extreme, or simply very strong, and it is often used like 'very'. This can be positive or negative. 'verblüffend' fits especially when something is surprising or unexpected. Learners may confuse the words because both express amazement. If the element of surprise is important, 'verblüffend' sounds more precise. If you only want to emphasize intensity, 'unglaublich' is more natural.
