World Align ensures consistent texture adjustment based on world coordinates. Usually UVs tend to break due to different rotations and different locations which would then need manual adjustments and tweaks of settings. Now you just select the object or desired faces and click a button that does that adjustment in a matter of a blink.
You might want to consider acquiring the UV Aligner addon, which includes World Align among its tools. UV Aligner can significantly improve your workflow by enabling precise adjustments to UVs, which are crucial for both hard and soft surface models – https://inletzone.com/mallet-uv-aligner
Using Cube Project is theoretically meant to be the default salvation, but it’s inconsistent and just cannot handle angles, while using it on separate faces always spells disaster, something that World Align has no trouble with and actively fights against.
