I don't quite think the Gigan update was better than the FW one, especially not the 10 Inch Gigan, but I do like the toy and its probably one of the reasons I love the character so much.
As a child I had like 3 6 inch Gigans. People kept buying me the same toy, but I kept opening them because my brother just liked to break toys as a child. RIP a number of my Trendmaster toys.
Here's a pic of the Bandai 6 Inch Memorial Box Gigan.
