I've got the following multi function laser devices, Epson AcuLaser CX11 (colour) & Panasonic DP-8020P (mono). Both are used at almost the same rate. But the black toner of the former finishes every 2 to 3 months, while the toner of the latter stays for years, and it costs 50% lower! At least I did not replace it in the past 12 months. This is not to mention the colour toners of the Epson.
What's behind this?
