Line6 is equally working to make their amp models sound like their reference amps. So are other companies.
You can find a lot of clips like the OP online where if listened with a good audio setup, they can sound pretty close with only subtle differences. This is good for us end users because it means we can pick whichever modeler we like and get great results out of it. I certainly have, having owned almost every Fractal model, Line6 Helix and QC. That's pretty awesome.
In these threads you tend to see people picking the "wrong" option (the device they don't own) and then backpedaling or putting out whataboutism to discredit the results. Just don't do that. There is no harm in admitting a particular clip was more to your liking than what you own.
Let's say you go to a guitar store and can try 3 different Marshall type amps through the same 4x12 Greenback cab. A Marshall, Bogner and Friedman. You are likely to find that one of these sounds best to you, in that room, with that cab, with a specific volume level and settings. Does that mean the others are not good? No, it just means you have a preference. Same thing with modelers.
My only modelers are Fractal because I feel they are the best compromise for me right now. No modeler is perfect, you pick which compromises work for you based on a variety of factors. If I could design a modeler it would be some hybrid combining features from Fractal, Line6 and NeuralDSP into one compact box.
