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.
