In the first six pages of the post Bunkermaster lists in the EL FAQ, there are at least forty different editors mentioned. As development on most of these has not halted, I fail to see why the thread would be invalid as a reference. While the feature sets and the "frontrunners" may well have changed, sticking any one of these into Google would shed some nice light on the subject.
