Our conclusion
Buy the TCL QM6K if you want the best picture under $500, especially in a bright room, and prefer Google TV with Chromecast. Choose the Hisense U6 if every dollar counts or you already use Alexa: it still gives you Mini LED, 144Hz and a two-year warranty, as long as you can live with the ads on the Fire TV home screen.
