Of the two, I've only tried Good Life. I found it more green than melony, and I found it too synthetic...that's why I didn't buy it.
For a melon note, two I'd recommend are Echo by Davidoff (correct me if I'm wrong, guys, but I seem to remember noticing melon in that) and Chic for Men by Carolina Herrera; this one is more subtle, a combo of sandalwood (or light wood) and melon, to my nose, but a nice balance, and quality.
I think a few more that contain a melon note are Acqua di Gio and Kenneth Cole Reaction, though I'm not sure about Reaction. Acqua di Gio might be somewhere between mandarin/fruit and melon or something.
