Which Go scoring system should a beginner use?

Either is fine — they rarely change the winner. Many beginners find Chinese (area) scoring easier because playing inside your own territory doesn't cost you points, so there's less to remember at the end.

Why is the komi different between the two rules?

Komi compensates White for moving second. Chinese rules use 7.5 and Japanese rules commonly use 6.5, each tuned so the game is fair under that particular way of counting.

Do Japanese and Chinese rules ever give different winners?

Very rarely, and usually only in unusual endgame situations. In an ordinary game the two systems agree on the winner, almost always by the same score.

Japanese vs Chinese Scoring

Go has two widely used ways to count the final score. Japanese rules count territory plus captured stones; Chinese rules count territory plus the stones you have on the board. They look different, but on the same game they almost always agree on who won — usually by the same margin.

Territory scoring (Japanese)

Under Japanese rules, your score is the empty points your stones surround, plus the enemy stones you captured during the game. Because playing an extra stone inside your own area fills a point of your own territory, you stop once your borders are settled. The standard komi — White's compensation for going second — is 6.5 points.

Area scoring (Chinese)

Under Chinese rules, your score is the empty points you surround plus the number of your own stones on the board. Here, playing an extra stone inside your own area costs nothing, because that stone still counts. This makes the rules simpler to apply for computers and beginners. The standard komi is 7.5 points.

Why they usually agree

The two systems count from different starting points but arrive at nearly the same place, because a point of territory and a stone on the board are worth the same in a finished game. The small difference in komi exists to keep the count fair under each method. For a beginner, the practical advice is simple: play the game the same way, and let the scoring take care of itself.
