The most important thing is familiarity. I mean, any of those would work, but the one that works best is the one you're used to. The brain is great at learning patterns, I'm extremely used to IntelliJ's classic theme (light) with Firacode with ligatures. But that's me, I've been daily driving that for years, so stuff just pops up at me. I like semantic highlights (i.e. something is static or a field, or whatever) rather than pure syntactic ones, but what matters most to me is stability. If it changes for no reason, it's jarring and takes a while to get used to it again.
