AWS L6 vs FB E6 scope

Looking to jump back to FB at E5 or E6. For anyone who’s worked at both Amazon and FB before, how does A L6 scope of impact and work compare to FB E6?

I know FB E5 is the equivalent level mapping for A L6, but I recall the scope was much smaller. I’m wondering if FB E6 would be a more appropriate fit?
