I don't regularly read much in the way of print news (I let the blogosphere digest stuff for me in advance), so I'm probably not the best person to ask, but 《财经》has got consistently good reporting, and 《炎黄春秋》 always has a couple of really interesting pieces in every issue. 《三联生活周刊》 is decidedly lighter, and is often worth checking out.

So far as literary magazines go, I guess I'm duty-bound to plug 《人民文学》, the Chinese parent publication of Pathlight, and would more enthusiastically recommend 《收获》 and 《万象》. (Actually, I haven't read 万象 in years -- it stopped and then restarted a while ago, and I don't know if the quality has been maintained.) 《读库》 is harder to find, but worth checking out -- it features essays on whatever topics the editor finds interesting at the moment, and has an interesting-stuff-to-boring-stuff ratio of about 1:3, which is well above average. 《天南》 is a new publication from Ou Ning that i haven't yet checked out, despite having translated a Sheng Keyi short story for their latest issue's English companion, but the table of contents for the current issue looks pretty compelling.
