It sounds like you're saying that because one is more expensive than the other it is therefore better.
But a 2k$ guitar is certainly better than a 50$ guitar. Not only in how it sounds but in how easy it is to play it.
My 1st guitar was bad so I couldn't do barrè chords. I thought I was bad and pros could do it. Turned out pros just had better guitars.
Better guitars also have less noise, better cables are shielded.
Yes, more expensive is better (up to a point).
EDIT: I should say the sound will likely better, not just better.
It's not just about the sound.
