For combat with more than 5 I will pull out minis. Exploration going into towns 99% theater of the mind
From a certain perspective, I prefer TotM because it's most adaptable, requires less prep time (I don't have to draw anything out, in advance or ad hoc), and doesn't run into problems with (for example) the Wizard player counting off squares to see how big his fireball is so that he can drop the boundary right between the Fighter PC and the troll she's in melee with.
