Visual Studio Code became famous over the past 3+ years I believe. The clean UI, easy to use UX and the plethora of integrations made it a very easy decision for us. Our gripe with Sublime was probably only the UX side. VSCode has not failed us till now, and still is able to support our development env without any significant effort.
Goland being paid, as well as built only for Go seemed like a significant limitation to not consider it.
I decided to choose VSCode over Sublime text for my Systems Programming class in C. What I love about VSCode is its awesome ability to add extensions. Intellisense is a beautiful debugger, and Remote SSH allows me to login and make real-time changes in VSCode to files on my university server. This is an awesome alternative to going back and forth on pushing/pulling code and logging into servers in the terminal. Great choice for anyone interested in C programming!
I chose GoLand because it is very feature packed for a very inexpensive IDE. The support team is very helpful whenever you run into an issue, speaking of which I have never run into any since I started using it. They also are able to provide free licenses to open source developers and students which is a big plus in my book.
