Personally, mapping Caps Lock to Ctrl (which I do anyway) and using Ctrl-C works best. I use vim and IntelliJ's vim emulation on an international keyboard where Ctrl-[ won't work.
So the entire argument about not moving one's hands is moot then, since in emacs you get navigation via control-key for free, and in vi you need to remap the most important key to something near home row.
I'm not interested in a war either. I'm only interested in both sides presenting fair arguments. If one side says "but the other side has to move their hands" and leaves out "oh, my side does too, unless I rebind keys", then that's unfair, and I'll say something.
If you think that places me on the other side of the argument (it doesn't), that's on you. It simply puts me in the middle.
