A few reasons. Like you said, syntax, wrapping and unwrapping is annoying. Also, RC doesn't cover cases with cyclic references. I think the difference is that for me GC is the default. For me, you need a good reason to not use a GC. Moderns GCs are very, very good and like I said I'd need a good reason to not use it. That's personal though, and I understand that not everyone agrees.

Yea, i can see that. As much as i dislike Go these days, their GC is impressive as hell. I can imagine future GC's will learn a lot from Go.

Has it improved? Last I heard Java’s tunable GCs still have much better throughput, while Go allows stack allocation more often.

(Yes, GC tuning is painful, but better than rewriting code hoping you might end up with the same behavior.)

What do you mean by "impressive as hell"? From my (limited) understanding Go's GC is average.

I don't know this field, perhaps my bar is low because of Python lol, but Go's GC has very short GC pauses. So short that it makes non-GC'd usecases less attractive imo.

My big issue with Go's GC, or GC's in general, is consistency. Go's GC can still be variable in pause time iirc. But it's been ~3 years since i've worked in it - so maybe my memory is wrong :)

From what I understand Python uses reference counting, which is a type of garbage collection that allows you to have deterministic performance, almost no "pauses" but at the cost of performance.

About the consistency, I think that's not a GC problem in general. For example, Java's ZGC has constant pause times: https://malloc.se/blog/zgc-jdk16.
