It's a common situation: you have two components that are pretty similar, they share the same basic functionality, but there's enough that's different about each of them that you come to a crossroads: do I split this component into two different components? Or do I keep one component, but create enough variance with props that I can alter each one?
Neither of these solutions is perfect: if you split it into two components, you run the risk of having to update it in two places if the functionality ever changes, defeating DRY premises. On the other hand, too many props can get really messy very quickly, and force the maintainer, even if it's yourself, to understand a lot of context in order to use it, which can slow you down.
