It's my preferred light oil. I don't much think any single product is a cleaner, lube and protector in the full meaning of those words. It's certainly true that Weapon Shield is a claimed improvement on FP10 and I suppose it is - there's some history there and it's all available. I am content to continue with FP10 if that's what comes to hand first.
To sum up I believe Weapon Shield is as good as it gets for light oil. That said I like lots of other products for lots of other purposes.
