It really depends. Some are shit, some are good. Usually you want the privileges of the merchants since they're really fucking great. Check the number of political power of each estate before you decide to give privileges, +50% power to the nobles is insane but +50% to commoners is nothing since their political power goes from like 100 to 150 out of 15k total. Values are also very important.
