Daily. Before leaving for work.
Same here. I generally don't shave on weekends and days off, though. My beard grows fast enough that it gets painful to shave after three days or so. I used a M3 Power for years, but it is getting hard to actually find those blades. The M3 Power handle can use regular Mach 3 blades, but they don't seem to work as well. Amazon has the blades for a decent price, but seems to have a problem with fakes.
I have used the Fusion and Proglide, and they work well enough, but they are expensive.
