I did work in the old days with paper strips and procedural boards, planner consoles and radar consoles with controllers working side by side
Now in TAAATS in Oz, I can honestly say it's like comparing appples and oranges. They are different systems of ATM. Electronic strips are for strategic planning and passing info quickly from sector to sector, centre to centre. Your tactical planning and manipulation of traffic is done by the label on the screen. That becomes your main method of info about each flight.
Electronic strips are not meant to be used like paper strips. Your label on the ASD (Air Situation Display) is the equilivant of your old paper strip. The electronic strip becomes the messaging system, abbreviated flight plan info, etc.
With both ways of ATM there are disadvantages and advantages. Personally, I prefer electronic strips and the system we call TAAATS in Oz (Eurocat 2000 made by Thomson/CSF and software by Thales).
