The Benq measured contrast will match or beat the Optoma when they're both showing decent color, but the Benq will look brighter and more natural. Both will beat the snot out of the Epson for actual contrast and the Benq has very good/low gaming lag. The Epson will have the worst lag and worst measured contrast by a large amount.
The 10,000:1 and 15,000:1 contrast numbers are all false because manufacturers are totally allowed to make up contrast results..so they usually choose to lie..badly. You won't realistically find contrast that high without spending $3000+. You can get a measured 4000:1-6000:1 by spending $2000-2500. For under $1900, you won't likely find better than 2000:1..usually about 1500:1 and flatscreen TVs are the same unless you're looking at newer plasmas or amoled. The cheaper LCD, like epson2030 are all lower than 1000:1, often much lower (except the 8350/8345 which is at or above 1000:1).
