Sennheiser HD 560s vs Hifiman Sundara

So last few weeks I've been researching, And coming from a hyperx user, my old one got broken so ordered newer version and it sucks,

So now I've ordered a pair of Sundara's for (248 USD) where I can try it for a few weeks then be able to return it so I'll try it anyways,but there's some ongoing discounts now on HD 560s for (175 USD)

What do you think is better guys? Especially its about 73$ difference, and when I was comparing without the discounts, it was only 15$ difference so said better get sundara

If for example sundara's are better 30% I think its worth it, but lower than that I dont know

Note: where I live everything costs a bit more, so usual 560s would be 150, but here the avg about 205$
