English has verb conjugations too. Grab, grabbed, grabbing etc. While we do have a few gendered nouns such as blonde vs blond. I will grant you gendered nouns on the whole, but you're still only standing on one leg (gendered nouns) which is a relic but overshadowed by any number of facts in Spanish's favor.
Spanish is mostly phonetic, which for dyslexics makes them easier to learn. This has been proven. The benefits to Spanish over alternatives are long-reaching.
Such as that English is a linguistic island or that Spanish orthography is objectively the best on Earth for natural, world-languages. It was also better put together with the inclusion of the '¿' '¡' marks. It's a fantastic piece of orthography.
As far as being a chore, if I didn't speak English or Spanish, I'd much rather be asked to learn Spanish between the two and would prefer to not waste my time with English or similar nonsensical language.
Mastery in any language is a lifelong effort but Spanish has the linguistic gold standard for its written form. While it's still another language and not 'easy', there are savings on effort and time overall to reach fluency. I speak both daily. In programming terms, it would be just "the best tool for the job".
Yes, but that has advantages of its own including you can speak more concisely in Spanish. Thus even that isn't a complete negative and it's probably Spanish's most difficult aspect to learn. English is going to lose to Spanish in a linguistic head-to-head on almost all fronts other than the fact it's more popular (a big deal in itself but that's not what we're discussing).
As someone who speaks both, and picked up Spanish later on in life (post-30), the fact I appreciate Spanish more as a language is a testament to its great design.
