So what's better to learn as a child, an easy to learn language or a really difficult one? Or maybe an easy one orally but a difficult writing system? I have no idea, but it's an interesting question indeed.

Spelling in English is an atrocious amalgam of contributions from a number of languages. My son is learning that in school so I am getting a front-row seat to that (especially given me out of work and remote schooling). He is constantly running into places where the rule he just learned does not apply.
Oddly, I have heard the argument before that Japanese and Chinese students are at an advantage due to the complexity of writing their languages. The argument being that their brans are being trained by that to work harder. I am not sure I buy either argument.
My kid is growing up bilingual, with English his stronger language. We both grouch about the "atrocious amalgam of contributions" that is the English language when he wants an explanation why the words 'rough', 'though', 'through', 'thought' and 'plough' all have different pronunciations.
Not disagreeing with you at all. Just wanted to point out another facet of the debate.
