It may just be a YMMV situation, went from 55 C1 to a 55 G3 and there is a big difference to me, also have a 55 G2 available that I rarely use now because I love the extra pop it gives(and the misses took over the room it is in helping to "justify" the G3 purchase in the first place). My comparison isn't apples to apples because I did not like using vivid on either the C1 or G2 but something about how vivid with some tweeks looks on the G3 just really does it for me. My totally unscientific brain thinks maybe the extra brightness makes everything still look good without looking overblown and washed out in vivid like the older sets did.
