Has anyone experience with Skyloong or Gammakay? - North facing LED

I have an Akko MonsGeek M1 V5 TMR (ISO DE) Akko AstroAim Magnetic switches and with side-lit south LED keycaps and I am very happy with this keyboard when gaming.

Since the selection of keycaps with a German layout is unfortunately very limited, I bought a Yunzii AL68 some time ago to get used to the ANSI-US layout, and it works wonderfully.

It's not a high end keyboard, but I didn't want to spend a fortune on testing the ANSI-US layout.

Unfortunately, I just can't get used to south-facing LEDs when typing. I miss the north-facing ones that I'm used to and that make me happy...

I just need my north-facing LED normal PBT keycaps where the legend is shine at the top and smiles at me. That may sound silly, but otherwise I'm missing that last bit of satisfaction.

Skyloong appears to use a different/its own gasket variant:

Soft Silicone Gasket The Skyloong O-ring gasket

Until now, I was only familiar with the classic gasket variant. Is the Skyloong variant just as good or not?

For writing, I would like a classic mechanical aluminum keyboard without HE/TMR that can be constantly modified with plates and other components and is THOCKY to the extreme.

If there's really no other option, then I'll just have to settle for a south-facing LED keyboard for writing, but that's just the way it is... Still, I think it's a shame that manufacturers (QWERTYKEYS, Evo, etc.) don't simply offer PCBs with north LEDs in their custom range so that you can decide for yourself what to buy.

I don't need a damn Cherry profile.

Does anyone have experience with one of these brands and a keyboard?
