The 4 points model is the first model which has been created.
Later, the 3 points model appeared. It works as well as the 4 points model but with only 3 LEDs (economies of current and material) and it's more difficult to get one LED hidden when you turn your head.
By now, we recommend not to use the 4 points model anymore .

For my personal experience, after 6 month of tuning, reading all the tips and faq, I can say that 3 points at the moment doesn't reach the tracking quality of 4 points, especially if you compares 4points cap and 3points clip.
IF someone doesn't agree with me, please tell me the secret to mirror the 4leds tracking quality in a 3leds clip
