I would say it's very useful when you are looking for one specific pattern, which happens a lot with Option<T>. Plus, being able to chain it in if / else if / else chains helps with organizing the code. It generally doesn't grow as deep as with match.
That said, match is fantastic and it's totally fine to prefer using it. if let and let else are there for those cases when you tend to discard or not need to use the other values than the matched one. How often that happens depends on what you are doing.
A "mantra" more programmers should have is to fix the cause of the issue, and not just the symptoms. You have to understand what the problem is to be able to fix it.
