Kashrut Standards in Israel

In terms of Kashrut standards in Israel, is it fair to say that the Mehadrin standards are stricter than the Rabanut standards? If so, should one choose a product or restaurant that has a Mehadrin hechser over one that does not?

Mehadrin standards are generally higher. In Jerusalem has a mehadrin division and a regular kashrut division. Many organizations only give mehadrin hechsherim. However, within the mehadrin hechsherim there are variations as well. Its a good policy for restaurants especially to look for a mehadrin hechsher, but that doesn't mean that non mehadrin is not kosher.
