“Used to” has several functions, for example to describe “being used to something:
I am not used to working overtime.
It can also come before a verb:
I used to live in Japan.

“Emmaville” used to be called “Vegetable Creek”.

“Would” has several functions. One function is to describe a repeated action in the past, whch no longer happens, for example:
I would take the long way and walk by the river if I had time.

The use of “would” is a little more limited tahn “used to”. “Used to” can be used to describe ongoing states like:
“I used to live there” but we do not say “I would live there.”
We prefer “I used to live there.
“Would is only used for actions like verbs of movement in this conversation with a South African Woman:
It used to be called the Western Transvaal
