If you shoot a lot, you probably need a crud-removing spray of one sort or another. (All brands do pretty much the same thing.)
Gun cleaning stuff is not something to obsess over. Instead, just make sure that you clean and lubricate often.

I use a really old-fashion material called Ballistol, which is high-quality mineral oil mixed with (I think) a little ammonia.
It cleans quite well, since it is a "creeping" oil which gets under barrel crud.
It also lubricates well enough.
I mention Ballistol only to point out that it's not the brand of stuff, or the kind of stuff, but rather the act of cleaning which does the trick.

Some firearms require more lubricant than others, Sigs for instance. Cleaner-lubricants are good to have but a quality gun oil and a tube of good gun grease should also be a part of your cleaning supplies......JJ

The G96 is good and smells nice. The cleaner part is for crud and residue not copper from the bore.
I would use a good bore cleaner and the G96 (if you like it) and not worry about it.
CLP (brand) is also good but still need a bore cleaner.
I have used the G96 and find it works well.
