I used to love SPA's but, in my experience, the most poorly organized SPA code is severely more complex than poorly organized server side rendered app code. With SPA's, you're usually dealing with some build system, a variety of dependencies, and a swathe of design patterns. At worst, you have everything located in a single file which has all of the above across tens of thousands of lines. With server side rendered code, you are (at worst) following someone's code that didn't follow the correct separation of concerns. At worst, the spaghetti code will be within a couple thousands of lines of code. I had a project recently where I ran into both of the above scenarios and I would prefer to debug poorly written server-side code than poorly written SPA code. It's night and day in terms of complexity.
