This has gotten alot of debate. The consensus seems to be that the Samsung is slightly better on upconversion (I can vouch for the fact that it is nice, since I own one) but it may also be the case that it is just different in the way it does upconversion, and so it comes down to subjective preference.
As for Profile 2.0, no one knows for sure if the Samsung is capable of it technologically, but it is darn close. Samsung isn't highly communicative about firmware releases either though, unfortunately. There have been some communications from LG that seem to indicate that the BH200 will be upgraded to 2.0, but nothing definitive--mostly short emails from customer support. (Check out the BH200 firmware watch thread.) Technologically, it has everything it needs, though.
