It depends on what you do with it, and how you use it. []*Person is a slice of pointers, they're small. []Person is a slice of structs, they're bigger than pointers.
The first requires a level of indirection to access, the second doesn't. The first requires no copying of structs when you're iterating or resizing, while the second requires copying entire structs. So, either could be faster based on what you do with it.
