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, the multi view and jump to source/output is great on big projects. Zotero macro is very helpful. Compile/clean buttons that also work on multi file projects are huge time savers.
