you don't have other ways to watch local channels like my situation, I feel you really don't have many choices. We use youtube TV simply because it carries local channels which is important to us.
My top free services are:
Tubi
Pluto
Roku channel
NewsOn ( can watch local channels of other places. We still care about a couple of places we used to live)
Crackle (Sony TV)
Kanopy (Basically it is just a library, old classic stuff).
America's Test Kitchen (PBS' very practical home cooking)
