Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Vim without a shell
When opening files from the file manager, it is still nice to have vim.
Pro Excellent performance
Because it loads the whole file into RAM, replacing all string occurences in 100MB+ files is quick and easy. Every other editor sort of died during that.
Pro Works on all platforms
Whether its your windows machine, a Linux, Unix or a Mac Vim would work everywhere. You can even build it from its source on your favorite linux environment.
Pro Has different cursor shape in command and insert modes
Unlike vim, gvim has different cursor shape in command and insert mode, which is very convenient.
Pro Supports all vim features and settings
All vim features, custom settings, and plugins are automatically available.
Pro Preconfigured emacs distro
Spacemacs is just a well-configured Emacs distribution with community-sourced best in class plugins and layers selected to take the setup pain out of Emacs. Evil mode gives the Vim bindings and modes for fast editing, while Helm makes everything discoverable to make learning to be more productive simple and unintrusive.
Pro VIM Keybindings with EMACS ecosystem
EMACS ecosystem and language support is best in show. The EMACS is a great IDE that was in search of a good text editor. Spacemacs makes EMACS have a good text editor.
Cons
Con GVim, like Vim, has a difficult learning curve
A lot of time is needed to learn all the commands and modes supported. A lot of time will also be spent tuning all the settings to the user's preference.
Con Emacs is slow
Emacs is single threaded which means that if you enable all the great features you might be used to from Vim, it will run noticeably slower which can be quite frustrating at times. There are efforts at a concurrent Emacs, but they don't seem to be going anywhere.
