There are some DLP's more prone to issues for sure, but it's pretty rare to see a problem on a new DLP unit. Also even if we just base it on the fact that the optics are not suceptible to convergence issues, that means fewer returns, and fewer returns means a cleaner RMA pool.
Even anecdotal can mean something when it's overwhelming. I'm not bashing LCD, I'm just saying anyone involved in projectors long enough knows it is the least reliable (although JVC LCOS might have to be put with the LCD's, but they don't get dust blobs).
Unless you have gone to every home theater/AV forum on the Internet, gathered data, created a spreadsheet and made it public that points to sources, then your observation is just a myopic view of failures to just this forum. Even that is anecdotal sense it's based on memory and not gathered data with sources and amounts of failures from a report.
If I based failures on this forum, then this would be the case:
Don't buy JVC/LCOS because the bulb will fail or dim in less than 200 hours. It will have chromatic aberration if the lens is not centered and you may see clouding in the corners or blooming around text.
Don't buy LCD because the bulb may explode and you might get a dust blob.
Also, you will not get perfect convergence with LCD/LCOS.
Don't buy DLP because the color wheel will fail, bulb will run hot, light leaks around the case, black level is awful compared to LCD/LCOS and fan noise is extremely loud.
Anyway, we can all speculate all day long but at the end of the day, it comes down to getting a product that reliably works for the individual.
