Like what has been said, there is so many opinions on this, you'll never get two people to agree.
But it depends on the intent. Hunting guns are different from varmint guns are different from certain competition guns. Type of barrel makes a huge difference too, between a factory barrel and a top shelf stainless barrel.
Since I shoot benchrest, I clean a lot. But a few fundamentals, a bore guide is a must, good solvent, patches and brushes, and a decent one piece rod(s). I won't name brands of things, just use common sense. You can't expect a barrel to perform well if it's fouled badly, just aint gonna happen.
