What is the difference between 要するに and つまり?


I read that 要するに and つまり are not always interchangeable. Still, I don't really
understand the difference between the two...




Not 100% sure on this, but I think `つまり` is used more for rewording something,
while `要するに` is more for "summing up" the "preceding" statements into a
"conclusion".
