Oodles and gobs are two popular words used to describe quantities of something that are quite considerable. However, there are several other synonyms that can be used in place of these words. For example, the words "plenty," "abundance," and "myriad" are often used to describe a large quantity of something. Other synonyms for oodles and gobs include "multitude," "mountain," and "heap," which emphasize the size of the quantity being referred to. On the other hand, words like "plethora," "excess," and "overabundance" are used to describe a quantity that may be more than what is required or necessary. Whatever word you choose, it's important to use the one that best fits the context in which it is being used.
