ZoZekool, you have been on here long enough to see that the majority find Lite-On better ( & it is for the price you pay).
It does just as well if not better than Plextor at all copy protections EXCEPT some music CDs (cactus data shield, etc).
Both are great companies though plex has had a reputation longer. Still for the price, you can always get yourself a Lite-On & a cd/dvd-rom player that does cactus alright for the same price often of one plex unit lol.
The rest will go down to just who you like better I think. Can't go too wrong with either.
