This is the problem with moral equivalence in judging media bias. One side can slide slightly left and still be almost completely factual (if slightly illogical), while the right can be neither factual nor logical - but we are made to pretend that the biases are equal here.
As a general principle, and I know it's not a very wise thing to say, left-leaning sources are on a different dimension of factuality than right-leaning ones.
I think that also depends on the story. You saw far different reporting on Covid from the two sources. Some of the stuff coming out of the right was crazy but some ended up being the truth and the left leaning sources clearly had their marching orders dialed in and even cast things that were eventually proven true to be “lies” at the time.
Crazy that ended up true? And what “lies”? In the country where I was back then (Hungary), it was quite different, but that’s also because abuse there was and there is still no opposition. COVID was just simply mishandled, and full of corruption, just as usual.
