I need to discover the semantic nuance between the phrasal verb "be accustomed to" and the idiom "get used to"!

E.g. please let me know how do the following examples differ in meaning:

• We've been accustomed to working together.

• We've got used to working together.

Or

• It takes you a long time to get used to it.

• It takes you a long time to be accustomed to it.

Or

• He got used to finding fault with everything.

• He is accustomed to finding fault with everything.

For me all three pairs mean the same and the only difference is that "be accustomed to sth" is a formal term in English! Although, I have my doubts yet!
