I use a combination. For the map, I use wet-erase battlemats (some pre-drawn), printed maps, fully-modeled terrain, and paper terrain. For figures I use miniatures and fold-up paper minis, along with tokens for swarms. I use print-out templates for most spell effects (I have multiples for those that stay in place, like fogs or wall spells). For markers I use my pad of paper 1.0 to write notes or a simple d20 next to the fig for damage done.
