Chinese and AGA scoring rules are essentially the same as Tromp-Taylor, just not expressed quite as concisely. AGA rules actually have a neat hack which makes it so using either area or territory scoring gives you the same result (by making you give an opponent a stone as a capture every time you pass). The reason Japanese counting is so complex is that there are situations where it would hurt you to play it out in order to determine life or death, as you would need to fill in your own territory, so they've developed a whole bunch of special cases to determine life or death for disputed groups without playing it out. Area scoring eliminates this problem, as does the AGA rule of giving your opponent an extra capture every time you pass. Really, if people are having trouble with scoring, just teach them area scoring and tell them to play it out until they can score the game unambiguously.
