They’re actually quite a bit different. Some of the obvious differences:
The Yuzu caps don’t have shine-through legends like the UHK stock caps. You also won’t likely be able to get the colors to match very closely.
The OEM caps are a bit taller than Cherry, so the Cherry F-row will be a bit lower than the rest.
The UHK caps have a rough textured feel, but the Yuzu caps are smooth.
I would suggest making a complete Yuzu set if you want the look and feel to be more normalized. Keep in mind that Yuzu doesn’t do shine-through legends. However, they have a sister company called FK Custom that does make shine-through caps, but they’re very different as well.
