Of the Assault maps (Hanamura/Volskaya/Anubis), Hanamura is my favorite. Seems most balanced. Breaking in point B isn't as daunting compared Anubis and Volskaya. Hanamura has like 6+ different entrances (right-3rd level, right-2nd level, right-basement, center, left window, left porch which also has 3 entrances to main room) to attack from and from multiple angles whereas Volskaya only 3-4 (right hall,elevator/window, main entry, left window) but all from same direction and anubis only 3 all from same direction (left hall, center, right hall).
As Defense I also enjoy Hanamura because imo Point A is not as daunting to defend compared to point A on Volskaya & Anubis. Defending point B is tougher but if you grind out the clock on A then it's not so bad. On Abubis/Volskaya it always seems like you need to hold Point B for 7 minutes.
