Eitherway, crackle, pop and hiss are often cause by mistreatment and an improperly adjusted turntable.
It's not right to think thit is 'what vinyl sounds like'. Loads of people do

It's also a misunderstanding that records wear from playing them a lot. They do, when you play them on cheap players.
But when your player has a proper arm is adjusted just right (it takes some time to do so, you can't do it without test records, bubble level and an oscilloscope),
records are pretty much infinitely playable.
I'm glad you still play records now and then, though
