At autozone the option is NGK V Power Copper Spark Plug and at O’Reilly and advanced auto they have the NGK V-Power Nickel Spark Plug

I don’t know if it makes a difference but which one is best for my stock 01 t/a, copper or nickel?

I use copper, and it does conduct electricity better than nickle, don't know if that make a huge difference in spark plugs or not. But more wires that transmit electricity are copper not nickle.

they are essentially the same plug. Both have copper cores. I would guess it just might be a marketing deal. NGK does not have a page for Copper plugs. Here is the NGK website nickle plugs. https://ngksparkplugs.com/en/product...el-spark-plugs
