使用FlexBuilder的主要原因：它有一个真正的调试器，您可以设置断点、单步执行并观察/编辑变量。

除非FlashDevelop已经开发出来，否则不要认为它已经拥有了其中的任何一个。

顺便说一下 - 如果你是学生/老师，FlexBuilder 可以免费获得。

Flash Builder 闪亮建造者

专业人士

• better debugging and profiling
• visual designer for MXML
• because of Eclipse: support for other languages (eg. with Aptana, PDT...) and usage of plug-ins for the Eclipse Platform with features not shipped with FlexBuilder (code snippets with CFEclipse "Dynamic Snippets", "auto-code" for getter/setters with Monkey scripts...)
• support of virtual folders/files (links to external files/folders handled intern by Eclipse, so also working on Windows)
• refactoring (renaming of classes, functions, properties with automatic changing of dependencies)

缺点

• Commercial license
• Big and because of Eclipse problematic with newer Eclipse versions for the FlexBuilder plug-in version (eg. not working with Eclipse Ganymede 3.4.1)
• adding and configuring the missing features with Eclipse plug-ins needs time and searching in the Internet (which plug-in? settings etc.)
• Code assist only average and sometimes buggy eg. if correct imports are missing ("java.lang.NullPointerException")
• missing of a code formatter or automatic get/setters (but there are solutions with other Eclipse plugins like Monkey Scripts, CFeclipse, Flexformatter "FlexPrettyPrintCommand"...)
• sometimes a bit sluggish if background tasks in Eclipse are working
• no package explorer
• AS2 and AS3 only - no Haxe

FlashDevelop 软件

专业人士

• free and Open Source (developed with C#)
• lightweight and snappy
• best available Code Assist for ActionScript
• supports all flash languages - AS2, AS3, haxe
• "auto code" for automatic getter/setter, variables, code for event handlers
• code snippets with integrated snippet editor
• extendible with plug-ins
• support for asdoc comments
• package explorer (show classes, symbols from a SWC file)
• basic refactoring
• multiple source code folders per project
• useful plugins : ANT integration, SWC creation, mini map, quick navigate

缺点

• only for Windows
• no visual designer for MXML
• no support of virtual folders/files inside the project
• weak refactoring
• changing classpaths must be done manually
• plug-ins often not working in newer versions and many plug-ins are only rarely updated
• limited support for debugging Haxe applications

普通的

专业人士

• projects for full range of flash apps : websites, AIR (desktop, mobile)
• debugging of FP/AIR apps with breakpoints and stepping
• debugging with watch windows and locals
• support for ASDoc comments
• automatic adding of imports and organizing of imports
• class wizard
• SVG/GIT integration

我不知道“Cons”是什么意思，因此无法翻译。

• no editing of graphics or animation (use Flash IDE for that)

概要

For debugging, visual design of MXML forms : Flash Builder 闪亮建造者

For coding AS2/AS3/Haxe projects under Windows : FlashDevelop 软件

Flex builder有一个用于MXML的设计视图，因此您可以更可视化地构建。另一方面，Flashdevelop是免费的！

我一直在使用Flash开发者，现在尝试使用FlashDevelop。FlashDevelop快速轻巧，正因为如此，我正在尝试切换。

我正在使用HG + TortoiseHG进行源代码控制。我有两个屏幕，所以使用外部源代码控制不是很大的问题。同时，通过不拥有所有小的源代码控制图标，IDE变得更加清洁。

DesignView有助于解决不具有集成设计的问题。

此外，我可以使用FlashDevelop进行调试并查看变量。我使用的是FD3.2.1。

除了已经提到的内容外，Flex Builder还拥有一些不错的工具，可以帮助开发者通过数据向导创建一个数据启用的Flex应用程序，并提供了一个良好的Web服务内省工具，可以自动为一个Web服务创建一个ActionScript 3客户端。

我正在使用新的Jetbrains IntelliJ 8，它非常棒（尤其是如果你习惯于Java开发）。它有比任何其他IDE更好的XML / JavaScript编辑器。

最新版本的IntelliJ也有一个很好的Flex/Javascript调试器。

这里有FlashDevelop（带Flex 3 SDK）和FlexBuilder之间的两个客观对比。首先，只有FlexBuilder包括AdvancedDataGrid。其次，FlashDevelop没有源代码控制集成。

AdvancedDataGrid并未包含在免费或开源的Flex 3 SDK中；如果您需要它，就必须购买FlexBuilder。（我假设如果您拥有FlexBuilder，可能可以通过其他SDK来使用它。）

FlashDevelop没有任何源代码控制集成功能，FlexBuilder则具有适用于Eclipse的现有、稳定的源代码控制选项，其中包括适用于SVN的Subclipse，以及许多其他选项。作为长期使用Visual Studio和Emacs的用户，在FlashDevelop中，离开编辑器进行检入让我感到不满意。

Flash Builder, even in version 4.5, has primitive, useless syntax coloring and customization features. From a 700$ package I was expecting at least what I can do with my free text editor. In the syntax coloring preferences, there is a total of 6 keywords, and you cannot add any custom one. How am I expected to code having variable names, function calls, and classes look exactly the same? I will stick to Flash Pro CS5.5 and SciTe.
