Alternatives are always good, as is competition. Go applies competitive pressure to others, just as they do to Go.
I really enjoy using Go as my main server backend programming language. It's verbose, but simple, and that simplicity makes it easy to maintain. The CSP model of concurrency/parallelism works really well at making multi-threaded applications.
In Go, I can pull from a work queue, fan out for parallel processing via multiple threads, fan into a smaller pool for some post-processing, really easily. In the HTTP engine, I can service each request with its own goroutine, which lets me write simple, synchronous, linear code, versus using promises or futures or callbacks in other languages, breaking up the flow.
To me, subjectively, it's the best backend language when I'm writing something from scratch and don't need to tie into a pre-existing ecosystem. Go exists because there are lots of people like me.
I'm one of those people. I've programmed in a lot of languages, but it wasn't until I was introduced to Go that programming actually become fun rather than more or less a job. Everything about the language just immediately clicked for me, and suddenly I wasn't thinking about the language, but rather what could I build (and I felt like I could build almost anything at that point).
Go is about efficient compilation, efficient execution, and ease of programming.
