I don't have either but both seem very similar spec wise.
The TS6050 has the benefit of automatic duplex (2 sided printing), where as the MX475 only has manual (flip the page over yourself when the software tells you).
The MX475 has an automatic document feeder for the scanner though, so that's somewhat useful if you scan a lot of paperwork.
If you never do large amounts of scanning I'd take the TX6050 at a glance. The print speeds, resolutions and paper size capabilities all seem roughly equal.
If you think you might ever need the ADF though then it can save masses of time. I've put around 15,000 pages through ours when I digitised a filing cabinet and it just wouldn't have been even remotely possible on a flatbed.
