I still prefer Acme to vim
One of my favorite things about Acme is that it requires basically no configuration, you can write small scripts to perform certain tasks, so in a way it is 'scriptable', but this are usually little more than shell pipelines to transform text.
I remember spending hours in vim simply looking around the huge mountains of documentation to find the right option to add to to my every growing vimrc, and when you wanted to do something slightly complex you had to use the rather bizarre vimscript.
Yes, vim has bindings for python and ruby and a bunch of other languages, but this brings us to another issue with vim: every installation seems to be almost unique, it has no consistent defaults, or even available features, so even carrying your personal vimrc arond (which is a pain in the ass) is not enough as it might depend on some feature not enabled in whatever vim binary you will find in a given system.
Window management and mouse chording in acme are simply a dream, while in vim i can rarely remember all the commands needed to manage windows, and the mouse is basically useless.
I could go on, but if you have tried both, you will realize that the differences are quite fundamental and even philosophical, so I don't expect every vim-head to understand and appreciate acme right away, because it will not fit with what they expect from a text editor.
All that said, I still use ed for quick edits, in part because it provides a consistent and almost universal interface, the trend some Linux distributions have of removing one of the most venerable and ancient Unix commands is very, very disturbing.
