how does tax at BL compare to Big4?

I have an offer for nyc big4 but my tax prof wants to connect me with some contacts at a couple BL firms.

In her mind, higher pay better.

In my mind, nyc big4 I can more easily transfer out to a Big4 EU office down the line (closer to family) after a few years in nyc, which seems worth the pay cut to me? (I’m not licensed in foreign jdx so it’s not like I could as easily transfer to a BL firm’s offices overseas). Am I missing something here?

Can anyone weigh in on the differences in assignments, clients, work flow/WLB, and/or exit options re BL vs Big4?
