LG Optimus G v Samsung Galaxy S III: Beast wars - GSMArena.com
You may want to read this. Despite the newer more powerful chipset, the Optimus G disappointed the guys at GSMArena. They were expecting something far better, not something that the 5month old SGSIII can still actually compete against with the performance actually being negligible. And to add the fact that LG completely sucks at giving device updates, I'd still say stay away from them.
