Which would you sell if you had both

Me personally, I would always get rid of the atomic breath repaints before the standard ones, I just like how Godzilla looks without it as a figure more.

I prefer the heat ray version for its more colorful palette, but that’s just me.

For me I like to have lots of versatility in my figures, and while it might seem counter intuitive for a goji figure I think the lit up versions tend to be the way to go for me. I like to show off a character’s powers even when they are in vanilla pose. For most hero types it can be a stand to make them hover a bit or some energy effects on the hands, for goji it’s the lit up fins, making it look like he’s charging up or just flexing for a pose. Besides that I can take him down and place him with a couple other monsters and the lit up fins will always look appropriate in the context of a fight, this only limits any relaxed or scene specific looks which I can usually live with. Either way this is my favorite Goji design and I think you’d be equally happy with the one you keep as remorseful of the one you didn’t

I think GMK has the best atomic breath repaint imo so I’d personally get rid of the original.

As far as heat ray versions go, GMK was a really good one. Tough choice but I’d still keep the standard version
