Yes, PlexWriter has pretty much always been the king of burners, and probably always will be. On that hand they are more expensive than most others though.
Not to say that Lite On isn't good though (though a guy I know had some bad things to say about the company's products in general).
I have a 32x12x48 CyberDrive. On the good side the tray opens smooth, the buttons and look are nice, and it only cost about $120 retail (very good price for the new 24-40x burners). On the bad side it's very noisy, it only has one colored LED, and it takes me about 3 and a half minutes (3 minutes and 30 seconds, about 200 seconds respectively) to write a 700MB CD-R. That's the total time Nero takes though (including caching the files, writing the lead in and out, and what not - total time the laser writes is probably about 3 minutes - I've heard some of the high quality 24x or 32x writers can burn a CD in 2 or 2 and a half minutes).
