Difference between [Select List (cascading)] and cascadeOption in a filter

[Sofia Grunspan]

Hi! I created a custom field (cascade type) and I created a filter that's going to be used in a automation rule to assign the priority value according to the field value.
Which is the difference if I write:
"Custom field name"[Select List (cascading)] in (parent list value, child list value)
and
"Custom field name" in cascadeOption (parent list value, child list value)
Which one will work better and why?
Thanks!

customFieldNameOrId in cascadeOption("JEFF", none)

Create a new filter with the JQL above, and be sure to replace customFieldNameOrId with the name of the cascading select field or Id that you want to query
