Upgrading front disc calipers worth it?

[DarkFlounder]

The calipers on my 72 3/4 4x4 are worn and due for a rebuild/replacement. So, I've got options.

Rebuild, replace, or upgrade.

I've got no problems rebuilding the calipers, but remanufactured calipers are so damn cheap ($23 each from Summit).

Then there's the upgrade option. Been looking at the Wilwood 2 piston bolt-on replacement calipers.

Is the upgrade worth the price? Looks aren't an issue (can't see them behind my steelies), so I'm interested purely in performance. Will they noticeably improve my brakes?

This is my daily driver, and I have no issues throwing some extra money at it when it comes to safety.
