Fancy aluminum battery terminals vs. Copper ring terminals?

[Bass911 10+ year member]

I know that the fancy terminals make the installation look cleaner than just stacking regular ring terminals. I want to know which has better conductivity? I'm pretty sure copper is better, but I want the Toolmaker style terminals. They do make copper Toolmaker stuff, but they are too expensive. My next question is a grounding question. If I use a copper ring 0 awg terminal to the frame with ofc wire into an aluminum distribution block, does the aluminum make ground worse or is it better conductivity to just cut out the distribution block?

copper is better but there's so much surface area that the difference is likely negligable

using your money for copper wire everywhere is much better to focus on

yep, that

The eagle has landed! They are not shiny at all, but a very dull brushed aluminum. The pics make them look glossy, but they are the exact opposite.
