I've never liked 5 GHz wifi that much, mainly because it never succeeded in its promise of offering more channels as many chipsets are crap and only work with channel 38, which undermines the whole point of having far more channels. It also doesn't seem to have the distance, nor even quite the speed in clear airwaves.

But boy, is 5Ghz ever less likely to get interference. Bluetooth, wireless audio (like some headphones), and wireless video senders can all totally wreck a 2.4 GHz signal. And even where that isn't true, there's only 12 channels so chances are someone's else is sitting on yours - probably at least three. If they're dual band, then they're probably straddling 3 channels at once.

With 2.4GHz wifi, you're at the mercy of not just your neighbours, but also your own stuff. In city blocks, using 2.4GHz can be almost impossible. And because interference depends on how much is being transmitted, that interference can depend on whether your neighbours are busy downloading from Steam or streaming Netflix.

Unfortunately, only way to get 5GHz on any hardware currently supported by MorphOS, and on MorphOS, is via an ethernet-wifi bridge. And support for it is still crap and may never get better.
