hey,
"instead of" contains "of", which should be followed by a noun. so, "instead of" should be followed by a noun (or by something that acts as a noun, such as some -ing forms).
on the other hand, "rather than" can connect just about any two similarly structured things.
nouns: i decided to purchase a truck rather than a car.
adjectives: i wish this transmission were manual, rather than automatic.
etc.
also, it can connect things that aren't technically the same grammatically but that play the same grammatical role. e.g.
it's best to read the passages quickly, rather than with precise attention to every little detail.
--> here, both the adverb "quickly" and the modifier "with precise attention..." modify the action of reading the passages. so, all good.
