All of the major brand newer burners are fairly equal. Some people like particular models because of various features like -rom, overburning, cd burning quality, rip speed, and availability of firmwares and scanning ability. It all boils down to what you want a burner for. I like all of my burners and use them all for various purposes, but I wouldn't trade any of them to make all four of them the same brand and type. Some burn -r's better, some burn +r's better. Depends on what you want to use it for.
