The difference is options. Developers can use anything on the back. You are stuck with JS on the front. That devs _choose_ Go means something.

You'd be surprised that the answer in a lot of times cooties just be hype or inertia. I've seen it first hand at an employer that supported both Java and golang. A new project was started in golang just because of inertia, whereas Java would have been a strictly superior choice on basically every front. The resulting code base was a huge mess, even as per the admission of the "lead" who made the original decision, who clearly had no business making that decision in the first place. Literally over a million dollars spent on a mediocre, unmaintainable result

So then it's just a subjective statement because whether or not you think the "design" is good, it's design is obviously practical, well liked and in heavy use?
