Whats the benefit to using monodevelope?

instead of unisciTe.

I am just curious.

Try it and you’ll see

For C#, and if you´re using Windows, none. Use Visual Studio instead.

But, if you´re on Mac and using C#, Monodevelop helps a lot since you have a good refactor and code complete with it. Like AcidArrow wrote, try it (or VS) and check for yourself.

I can´t say anything if you´re using UnityScript.

Although I use Visual Studio exclusively, I would assume Monodevelop has similar features. That is: code completion, better syntax highlighting, refactoring tools, plugins to maximize your productivity, better management and navigation of multiple code files, external compiling of code (to catch errors before it even hits Unity) etc.

It’s like the difference between Notepad and Microsoft Word.

There are some tweaks you can add that make UniScite at least legible (search the forums for some threads on the subject). If you want a simple / powerful text editor (no debugging), then Notepad++ (there are tweaks posted in the wiki) or the “Unity Script Editor” (also in the forums) that’s designed specifically for Unityscript.
