I can't really compare anything to G96 CLP because I've never tried it, but it does meet the same MIL-PRF standard as Break-Free CLP, for what it's worth (not a particularly challenging performance standard in today's world). That doesn't mean that they're the same, of course, but they were designed with the same or similar specs in mind, so it's interesting that Break-Free is currently the runaway winner in the poll. Maybe it is a lot better at cleaning, but only those who have tried both can say with any conviction. I haven't used either in my guns, so
that's all I have to say about that.
Currently I use Weapon Shield CLP to clean, lube certain moving parts (rarely and sparely), and protect the bore. I use Weapon Shield Grease to lube the slide (takes extremely little for that) and protect against corrosion (smear on, wipe off--seems to protect as well as Eezox but without all the nasty chemicals and their odors). The grease is optional and is a personal preference for grease over oil--WS CLP also lubricates extremely well, and is better than average at corrosion protection (albeit not as good as the grease in this regard). WS CLP may not be the best general cleaner, being a somewhat heavy lubricating oil rather than a solvent, but after you use it for a while, the gun seems to become easier to clean. I haven't used a strong solvent in months, and hundreds of rounds (maybe more than a thousand) later, my defensive pistol's bore is still shiny with no scrubbing and not many patches needed. Whenever there has been some bad metal fouling (seems to depend on the ammo), I've used Bore Tech Eliminator, which does a pretty thorough job of breaking the gunk down and getting everything squeaky clean with minimal hassle. By the way, all of these products are non-toxic and safe to use indoors without anybody screaming at you because of the smell.
Regarding Ballistol, the last entry in your poll, it's actually pretty good at cleaning even the heavy stuff, but it might take some time to start working, as well as a little effort. As a general everyday cleaner, it works fine in my limited experience, and several people have compared it favorably against both Hoppes No. 9 and Break-Free CLP in this regard. As a lube it seems to do the job well enough (I've used it on some squeaky hinges with great success), and it will also protect against corrosion. I haven't used it much, mostly experimentation, but plenty of people swear by it once they've tried it, and I think it's good enough to use exclusively (as is Weapon Shield CLP). It's also non-toxic, being composed of pharmaceutical-grade white mineral oil, oleic acid (a base component of olive oil and a number of other plant-based oils), several different types of alcohol, and a few natural essential oils.
Another product that may interest you if you prefer strong cleaning properties in a CLP is Gunzilla. I've only played around with it a little bit thus far, but it seems to have solvent properties and really cuts through crud. I'm always wary of products that have an unknown composition, but it seems to be a vegetable oil fortified with cleaning and dry lubrication additives, and is supposed to be non-toxic. If you believe the testimonials, it's apparently had a good deal of success on the battlefield (Weapon Shield CLP as well), being greatly preferred over the G96 or Break-Free CLPs. It's thin and kind of makes everything feel greasy even when it's mostly dry, which I guess helps under very dirty conditions (you can also wipe Weapon Shield CLP off, and it still seems to keep lubricating for a while).
By the way, you could probably get free samples of Weapon Shield and Gunzilla if you write to their owners/inventors:
