Netherite is worth the time, its such a good ore in my opinion and I believe personally it'll change minecrafts meta for ages.
I'll love if minecraft adds more ores, even though its against the games original form. Vanilla is super boring unless you are a very good builder or have good connections where you can play with friends on servers.
Also Netherite looks more tactical and awesome than diamond, it gets my vote because of its unique armour form and colouring.
