I don't think anybody is arguing AMD have better Raytracing performance being one generation behind but the 6800XT and above cards Raytracing performance is not "crap" like you and others are making out.
Nobody for example argued 2080TI raytracing performance was crap before, it's still not crap just not as good as the newer gen from nvidia. If for example you plan to work on UE4's raytracing the 6000 is good enough. If you want to play that Cyberspunk flop at the ultra max RT settings in 4k you may be slightly disappointed.
QUAKE 2 RT, minecraft, fortnite, control, cyberpunk are RT games that AMD cards will struggle just top of my head, and yes, people been arguing that Nvidia TURING cards had bad raytracing performance since the very start lol
