I like the charcoal ones of course. But I find the gga to be fine if you are not to worried about grill marks. I have been experimenting with several gga to get better heat and to get them less sensative to wind and blowing out. Had to stop due to other issues like getting my little shop organized. I also have seen pics of the newer gga and they show more of a grill mark/char kind of thing going on but I don't have one so can't say for sure. But I would say you need both. I find gga rather often at second hand stores, not so much the charcoal one. All mine have been cheap finds except for an unused very early one that I paid $30 for. Otherwise they are in the 6 to 12 buck range.
