That strongly depends on the situation. You don't have a lot of smaller spaces like in HM, so you often simply can't clear out a room by dashing in and melee-ing and throw shit at enemies to clear out the room. Because of the size of rooms, the amount of gun wielders walking around and the amount of glass walls, having to often rely on luring them to you cautiously can become a bit boring due to its slower pace.
Just went through what I think is the final flashback mission. Ooh boy that was not fun. Too many open spaces and glass windows.
