There are others here with more experience, but I have both and here’s my take, for what it’s worth.
Banana tends to be a brighter more yellow color as it ages and responds well to lightening color genes like pastel.
Coral glow is more creamy like a lav albino as it ages and benefits from darkening genes for contrast.
Both have some effect on pattern, both develop the spots, more or less, in the single gene form. Both are “sex linked” as far as we can tell.
Mixing the two gives you the super form, it tends to develop few if any spots. But I feel like the mixed super form is just a bit “muddied” compared to the line pure forms, but that may just be me. Most of the breeders I’ve heard discuss these genes advocate keeping the lines separated. I’ve noticed that when there are obvious lines, the community generally sides with keeping them separate, but that may just be an outgrowth of the seemingly endless desire to discover the next hot new gene or make a “world’s first.” No great crime to mix them, just not popular.
Lastly, many people don’t see any difference at all. They just list the offspring as whatever they want, banana is the better known, coral glow the more “rare.”
