I would like to discuss some things first, before i make my decision.
Both of these phones, rocks. But.
What's your daily usage when we're talking about smartphones ?
If you're going to use it a lot, i would prefer LG G2. Because, the general perfomance of the phone is better than the HTCs. As you can see here, the LG G2 has some precedence against the HTC. I'm not quite sure, about the brightness of the LG. You can check some reviewes too, to discover it.
