really depends on the map, but eqiupment interaction is usually the one to go for. for example in withdrawal you WILL need maximum equipment interaction speed because bagging cash, searching computer, power box, alex shaw disguise gets affected by it you will also need a lot of sprint time because of the cash carrying. ( and be a technician) for other maps though, use an infiltrator instead. but equipment interaction is super super important for the smallest interactions, etc. photograph removing in financier, cashe. power box rewriring in scientist, lakehouse. screwdriver speeds in scientist, the cashe. It is just very useful.
