Upgrading from 4 piston willwood brakes to 6piston, is it worth it?

Well I have not been able to, yet. I am currently deployed and I am anxiously waiting to drive my car. I was just curious, I had a great deal on the 4 piston variants with my restoration. I wanted to know if it was worth the upgrade or if it would just end up being an aesthetic upgrade. I was driving a 2008 BMW and had no problems obviously, but was curious with an older car that does not have ABS, traction control or a booster, if it would have issues slowing down at those speeds.

Thanks.
