texstudio is easy to use and its also free.
TexStudio is my best choice
LyX is the most human beings for TeX beginner like me :D
I use Linux for many years of conviction. I started using Texmaker but had some errors, then I went TexStudio information which I believe is the best LaTeX editor. Who is user windows is quite a problem but if Linux is used things are much easier, faster and lighter.
If you require a LaTeX editor able to preview inmediately the output, I reccomend
For a detailed list comparison, see the link
For a month now that I've change my editor from TeXStudio to SublimeText + LaTeXing which makes my writing much faster.
I usually use Kile (Linux, KDE Applications), but you can also try: Texmaker, LyX, LEd.
TexMaker is the best free Mac IDE.
I have used TexnicCenter and TexMaker on Windows OS but I prefer the interface on TexnicCenter.
TextStudio is working fine for me
I have been using Lyx since 2009. It is really good for people who don't have any previous experience with latex, although at the end, you have to learn latex.
I'm using Lyx editor.
If your document doesn't have too much big .tex and .bib files you might like some online tools like https://www.sharelatex.com/, or http://docs.latexlab.org/docs (but you need a google account for the last one). It's nice if you use several computers/tablets, you have nothing to install.
For simpler editing and note-taking needs on OS X, I wrote Archimedes: http://www.mattrajca.com/archimedes/
I have no doubt in recommending TeXstudio because it is a very friendly to write platform. Look I'm a lawyer and I have many technological knowledge but this was the smallest tasks and problems brought me and not change it for anything.
I agree with Mr. Loayza. In my opinion TeXStudio is the best IDE for LaTeX. It has nearly all of the frequently used symbols visually represented for ease of access.
@Troestler Christophe . Please what are the steps of installation to try your suggestions?
Lyx makes life easy. I recommend LYX
For years, I've used WinEdt. I'm now playing with TexStudio.
The Eclipse extension TeXlipse supports bi-directional lookup between PDF and TeX source code and underlines errors in the code. It also allows you to edit multiple documents and/or open multiple views of the same document at the same time.
