Unicode is a much more comprehensive character encoding system than ASCII, which only includes a limited set of characters primarily used in the English language. Unicode, on the other hand, includes characters from a wide variety of languages and scripts, making it a much more versatile and globally inclusive system. In today's world, where people use different languages and scripts on a daily basis, Unicode is generally considered to be the better choice for encoding characters. However, ASCII still has its uses in certain contexts where only basic English characters are required.
