Best keyboard for 3D modeling ?

Hello to all of you,

I'm going to change my keyboard soon and I was wondering if anyone knew one that is particularly suited for 3D modeling.

I was wondering if having macro keys like on the Corsair K55 could be useful and if the mechanical keyboard have an advantage over a standard keyboard. I was also wondering if buying a high-end keyboard at 250€ (ex: Razer BlackWidow V3 Pro, Corsair K100...) was worth it? Or if it was better to invest elsewhere (GPU, PC screen...). I've always used low-end keyboards so I don't have much to compare it to.

Thank's in advance for your answers,
