Both are fundamentally different, neither is "better". They are both good at slightly different things. If your desire is to accept bytes over the network and spit back bytes over network Go is going to be a pretty solid choice because that was very much the focus of it's design. However if you want to build an application for a hard realtime environment and you either lack the space for runtime or can't handle GC pauses then maybe Rust is a better choice. From a language perspective Go is a simple language and Rust is a complex language. The two have different tradeoffs here. Go is easy to learn, has limited pitfalls but also lacks in the power department if you need metaprogramming and abstractions to model your problem. Rust however accels in that role due to it's powerful type system and hygienic macros. The tradeoff is very apparent once you try use the two languages however, Rust is -far- more difficult to both climb the initial learning curve and has a much higher ceiling. Fundamentally you will probably find Go is better at replacing dynamic languages though there are many cases where C/C++ was used where it's bare metal nature isn't needed and Go is a very suitable replacement. Go however has some difficulty in replacing certain usages of C/++. Namely it can't easily be used to create a shared library because of it's runtime and I/O system. That said if you wanted to be able to replace any and all C/C++ code Rust would be a better choice as it can do anything C/C++ can with no downsides. i.e embedded systems, shared libraries, bare metal access without worrying about the green threaded execution model. There are many other things to consider too but these are some of the important ones from someone who got into coding doing C and embedded, has since learnt both Go (and used professionally) and Rust (and used for side projects). Subjectively I think Go is a better choice when it can do the job as it's easier and less brain intensive to just do the thing. Rust however is more "fun" to program in as it's a less mechanical endeavour and also can solve some problems you can't with Go.
