I started with TeXworks (+ XeTeX, which both happen to have been created by Jonathan Kew) and I found no reason to change since then. The only slight drawback is that autocomplete support exists but is rudimentary, however it doesn’t bother me that much.
Which editor do you prefer?
TeXStudio for the convenience of compiling and managing multi-file projects; (neo)vim for serious work with the tex files.
