I find controlling less 'fun' than with paper strips, and using EFPS does introduce some mental friction over paper. All other things being equal, I would go back. Of course, the electronic environment means that things aren't equal; interfaces with CFMU, CDM etc would be impossible with paper.
Just make sure that you have enough resource (i.e. software engineers) to make all the changes and updates you require. There's nothing more frustrating to identify a major issue and be told "Maybe next year, and it will cost x thousands of pounds" and then having to try and justify your need.
