Impact on standard category field in service request object

Content

Hi Team,

I want to know that which is the best way to maintain SR types either using the standard category or by creating a custom field.
Because now I'm using standard categories which requires business unit to create.We have multiple business units and the visibility is restricted to other BU agents.
Service request types value might be Fault,Query,Fix,Enhancement and all BU have the same.

So is there any feature will get affect if I using the custom field to maintain the category values?

Please advice if anyone aware of this.

Thanks,
Shaheela
