The wikipedia article on Lost work lists much more Ancient Greco-Roman works than Chinese. The vast majority of Classical works haven't survived, even of the Big Names like Aristotle and Sophocles. Although most Wikipedia editors are from the West and presumably more familiar with Western Classics, so its not necessarily comprehensive.
From my understanding, there doesn't seem to have been as huge of a loss of Chinese works, but this could just be that I'm less familiar with them. There could be reasonable conjectures as to why more Chinese works would have survived- superior printing press and paper technology, and a more stable polity would contribute.
I was wondering if there was any truth to my impression or if it was just a biased sample. Were Chinese classical texts better preserved than western ones?

Bingo. Lost ancient Chinese texts are less known in the West than they are in East Asia. Much of pre-Qin philosophy (with the notable exception of Confucianism, Legalism, and Taoism) was lost to censorship and suppression under the reign of Qin Shi Huang. There were what Chinese historians called a "Hundred Schools of Thought" in China prior to the Qin unification of China (Mao's famous quote "let a hundred flowers bloom" is meant as a literary allusion to this period). Besides Confucianism and Taoism, there were the philosophies of Mohism, Legalism, School of Names, School of Yin-yang, School of Agrarians, Eclectic School, School of Diplomats, and the School of Small Talks. We know very little about the School of Names because their main text, the Gongsun Longzi, is lost, and what we do know is nearly undecipherable.
However, there's a good chance of there being major archaeological discoveries in the future. The rapid growth of Chinese archaeology has led to some major finds in the last few decades. Sun Bin's Art of War was long considered a lost text, until it was unearthed in the 1970s. And as recently as 2008, archaeologists discovered a large trove of pre-Qin bamboo slips donated to Tsinghua University. The New York Times has an article with quotes of historians explaining the significance of the find.
