Best premium full-size keyboard under €300 for tactile switch lover?

Hi!
I’m looking for a premium full-size keyboard (100% with numpad) for my boyfriend, with a budget of up to €300.
He currently uses a Corsair K70 Core, and I want to get him a real upgrade, not just a similar keyboard.
He mainly plays Valorant and Minecraft.
We tested several switches in stores, and his favorite was the Razer Purple clicky switch. He loved the tactile feel under his fingers more than the click sound itself.
I’m currently considering the Keychron Q6 Ultra 8K with Silk POM Banana switches, but I’m not set on it.
Would you recommend the Q6 Ultra, or is there another premium full-size keyboard (available in Europe) that would be an even better choice? I’m also open to other tactile switches if they match the feel he’s looking for.
Thanks!
