So with this being said, which of the two brands has the better dvd burner?
better in what way? this is all really relative. the innovations benq is introducting like the improved disc spindle and solid burn are all really quite impressive. but being so new, do these new changes affect the recorder in some way, will it lengthen or maybe even, shorten, the recorder's life? we really don't know the answer to that yet.
performance wise... i've seen the benq 1640 give better numbers in dvd burning: faster burn times (but only in the seconds.), less errors, etc. etc. but in my opinion, the differences are so small they are negligible for a home user.
on the other hand, the lite-on has a reputation for having an RPC2 code that's easy to crack (kprobe is all you need to free it) ... plus most of its models outperform the 1640 when it comes to burning on regular CDs. again, the difference is so minute. it's negligible. (quick note: while all lite-ons have smartburn... not all of them have hypertuning or overburning. so check before you decide.)
i will however caution you against getting newer models (beyond 1640) from benq. i have read in some forums that they have switched to panasonic chips. (i heard that's why the 1655 is not turning up quite as impressive results as it's older 1640 cousin) while lite-ons continue to use the "old-reliable" mediatek.
you will never find an ALL-IN-ONE dvd recorder. (at least not yet) there will always be one thing in which another drive is better at.
so in truth, its an even playing field out there (provided you are not looking into getting cheap generic ones). like i already said in earlier post... assess your need and list the features you want. after which, you should check which drives are available for you and fit your budget then make a decision you are comfortable with.
while i am lite-on user, i cannot properly reply to the allegations of "mapili siya sa media"... that's because, for the sake of compatibility and less coasters, i NEVER buy recordable dvds priced less than 10-15 pesos. i have coasters, i'll admit, but it is more because i had some "software" problem (incompatible IDE drivers with nero, power outage, etc, etc) and not because of the drive per se.
just a thought... exactly what lite-on model are you considering? maybe if we knew, we can better assess your dilemma.
