You will not find "the one and only best" of anything. Just peoples opinions. In reality, most everything works just fine these days.

Learn how to take care of a rifle and shotgun, but don't obsess over which specific products you buy to do that "taking care of".

The things I use most are Hoppe's #9, RemOil, and Breakfree CLP. But your choices are wide these days and many many things will work just as well.
