a) You are still coding somewhat, but just prototypes. It is fun to use the APIs your company builds and help customers with it b) You learn a ton about business. I would call this position more professional consultant, since in the right company, you learn about deals, how much a company pays for what and what value they get out of you
You finally work with people and not nerds who never grow up. You can touch code, but also learn soft skills and make connections. Personally, the money was equal if not better. You finally work on the profit center of a company and not the cost center. After I switched to Solutions Architect, I come here every now and then and be so happy not to do this fulltime anymore. I don't care what you build at the weekend anymore.
I am also more free after work. There is no special new tool I need to learn after the job to get a job in 3 years from now. The people skills I build with my wife, kid and friends are so much more valuable now. So socializing replaced hacking on a new project. Which also did good for my mental health.
