The difference between an IDE and a souped-up vim or emacs configuration is ... very little. Your average fancy pants vim config has auto-completion, debuggers, etc.
I find that spinning up QtCreator on a new machine is orders of magnitude faster than transporting a vim configuration.
Sure, there's some initial setup time but I'm not seeing how its orders of magnitude faster unless your vim config is super bloated and/or has a lot of external dependencies.
