I also own a TCL Roku TV and the interface is easily twice as slow as my Roku Ultra. Right on the home screen is a giant ad(unless you have network adblocking). Over the years Roku and Google have been fighting about Youtube/Youtube TV on Roku, just like Disney/ESPN fought the cable companies.

I also own a Toshiba built FireTV that suffers from those same problems but far worse. Way more ads, much slower interface, and the hilarious part is a hidden power off button in the menus(it's fun trying to turn the TV off without the proper remote).
