I agree. For an inkjet all-in-one, I'd recommend the Canon MX882 or its follow-on models. The printer is fast and high-quality, and has a bypass input slot and a duplexer. The scanner is as good as any standalone consumer-grade photo scanner you can find nowadays—which is not a given in the multifunction machines—and it has an automatic document feeder with duplexer. It has wired and WiFi networking, and it generally just works.
My place of work insists that I have a Brother MFC-J5910DW as a home-office printer. Next to the Canon, it's a piece of crap. The print quality is atrocious. The paper tray was designed by a sadist. It jams far too often—I don't think I've ever had a paper jam in the Canon. While it can duplex print, the ADF cannot duplex scan. Scans are washed out with poor color fidelity. The front-panel interface has a strong affinity for fax mode, even when there's no phone line connected: if the thing's been idle for any period of time, it's in fax mode the next time you try to use it... and if you push a different mode button to wake it up, it give you error beeps until it finishes waking up and starting fax mode. At least once every 48 hours, it startles you by entering a loud self-cleaning cycle that purges a little more ink from the system.
