Strictly gaming perspective...
Generally speaking DLP is the superior gaming tech but there are exceptions when it comes to input lag (not so much regarding motion where DLP is basically still king of digital projection).
One of the better inexpensive 1080p DLP PJ's for gaming is the BenQ w1070, input lag is in the 20ms to 30ms range.
For LCD the older Epson 8350 is excellent regarding input lag (20ms range), as is the even older Panasonic AE4000 (30ms range).
I have played on the 3010, 5010 and 5020 Epson's and while the lag is detectable it is not likely to bother casual gamers or those that do not play competitive online shooters/racing/fighting games.
Out of the newer roughly $3K models only the Sony HW50 offers decent input lag at around 30ms.
Avoid the JVC's for gaming due to both input lag and motion handling.
If you want a truly lag free gaming experience from a digital PJ the Optoma GT750 is about the best I have used (although it falls behind the others mentioned regarding over-all image quality).
Many of the inexpensive (1280x800) 720p LED DLP units also have minimal input lag (in the 20ms range).
* Regarding sharpness, generally speaking single chip DLP is sharper versus 3LCD but this can vary unit to unit due to lens quality (CA) and convergence (on the LCD).
