You are comparing the outgoing flagship model (at least in Malaysia) from Toshiba with the "just coming" entry model from LG.

From the specifications point of view, the LG overwhelms Toshiba. LG 100K contrast versus Toshiba 50K. Toshiba panel response speed 7 ms seems pretty slow to me. I don't know the spec for LG though.

But looking at the picture quality, Toshiba gives a softer and more natural looking colours (or is it just my perception?) In my opinion, LG gives a sharper and brighter picture. At the end of the day, trust your own eyes to decide, which is better. If you do not trust your own eyes, bring your wife (or your mother, girlfriend or sister) to the showroom. Women (some of them) can be quite sensitive to which looks better.

For both brands, there will be customers who have voted for them with their wallet and believed that they got a great deal. So you cannot be wrong either way.
