'erheblich' and 'dramatisch' can both describe a major change or a large extent. 'erheblich' sounds factual and more neutral: it simply says that something is clearly large or important. 'dramatisch' is stronger and often has a negative or serious tone. It is especially appropriate when a development is sudden, serious, or worrying. For normal large differences, 'erheblich' is often more precise; for serious crises or strong negative changes, 'dramatisch' fits better.
