I used to shave every second or third day with a Sensor. So far since starting DE shaving I've been doing it daily and I've only missed one day, and that was due to a lack of time rather than needing to give it a miss. One thing I really like about DE shaving is that you can control how much stubble to remove, my cartridge used to irritate me no end so I couldn't do it every day, whereas if I get irritated with a DE I'll just have a light shave the next day and all's right with the world.
