For comparison purposes: The best code I have ever read was written with Sam ( http://sam.cat-v.org http://sam.cat-v.org ) by Ken Thompson, the second best code I have ever read was written in ed(1) (by Ken and Dennis Ritchie), and the third was probably code written by the rest of the Plan 9 team at Bell Labs written using mostly acme ( http://acme.cat-v.org http://acme.cat-v.org ).
P.S.: Both sam and acme were written by Rob pike (ken wrote ed), in Plan 9 circles some people would call acme 'an ide', and while I use acme, I would consider sam a better text editor in part because it is precisely just: a text editor and nothing else.
