When comparing Visual Studio vs Eclipse, the Slant community recommends Visual Studio for most people. In the question“What are the best third-party IDEs for Unity?” Visual Studio is ranked 4th while Eclipse is ranked 9th. The most important reason people chose Visual Studio is:
If a project type or a platform is available for C#, it's available in Visual Studio. Some IDEs and code editors may cover some project types, but Microsoft always starts with VS. If you work with a cross-platform technology like ASP.NET MVC, it matters less. If you work with Windows-only technologies like UWP or WPF, you have no choice really.

Pros
Pro Official IDE developed by Microsoft
If a project type or a platform is available for C#, it's available in Visual Studio. Some IDEs and code editors may cover some project types, but Microsoft always starts with VS. If you work with a cross-platform technology like ASP.NET MVC, it matters less. If you work with Windows-only technologies like UWP or WPF, you have no choice really.
Pro Free Community edition
Community edition is almost Pro edition, with just a few exceptions. Unlike old Express editions, it supports plugins.
Pro Amazing coverage over languages
Supports many types of C, and java, as well as ruby and python.
Pro Excellent and broad range of plugins
The plugin development ecosystem is very mature and covers a lot of use cases. For example, it is often easy to find a plugin which allows you to have the keybindings of your preferred editor.
Pro Partial cross-platform support
Visual Studio runs on Windows and macOS, so even if you develop on a Mac you can still develop with Visual Studio.
Pro It can run c#, c++, etc.
You can use too many programming lang. And you can select them! Like "I want to do this, not this".
Pro Cloud storage
Your Visual Studio Online account gives you a place to store your code, backlog, and other project data with no servers to deploy, configure, or manage.
Pro Supported by ReSharper and other plugins
Code productivity tools improve code editing experience greatly, provide static code analysis, refactorings, navigation etc. They are considered by many developers as essential.
Pro Fast-paced development iteration
Fast-paced development iteration from the Microsoft team, with new versions and fixes almost every week.
Pro Comes With the .NET Framework
Pro Product backlog
In agile development teams one really needs features such as product backlogs where you can assign features to team mates and track their progress on them. VS provides a web based interface for you to track your team's complete progress on the project.
Pro Fast
Pro Time travel in debugging
Pro Great UI for nugget packages
Pro Flexible to install/adjust payloads
Pro Same excellent Roslyn compiler/editor as VS for Code + powerful debugging tools
Pro Good support and community
Pro sda
Pro Free and open source
Eclipse is an open source project and free to use.
Pro Multiple languages - one IDE
Pro Large selection of plugins
Eclipse has a large and active community, which has resulted in a wide variety of plugins.
Pro Fast compiler
Eclipse uses a custom compiler (which can also be used outside of Eclipse), which is often faster than the normal Java Compiler, especially for incremental compilation.
Pro Easy to use and get started with
It's interface is super easy to use, after adding required package for your task everything just works.
Pro Gives good perspectives on your project
The concept of perspectives is outstanding. It puts right tools at your fingertips, keeping the tools you currently don't need out from the workbench. For example, in VCS perspective it's all about versions and branches. In debug perspective it's all about state.
In java ee project it can show http endpoints in a very accessible manner.
Pro Highly customizable
Thanks to the large variety of plugins and various configuration options, Eclipse is very customizable.
Pro Great debugger
Shows threads, concurrency locks, and conditional breakpoints.
Pro Good font rendering
Because Eclipse is based on SWT, it uses the native font rendering and thus looks better than other IDEs on some Linux systems, where the Java font rendering is not optimal.
Pro Good refactoring tools
Pro Faster than any other Java IDE
Fast, suitable for big projects, customizable, supports UML, many programming languages, plugins, and widgets vs NetBeans and JDeveloper. Support for Workspaces and Perspectives. Long term tested, free of charge, vs IntelliJ IDEA.
Pro Great in-UI documentation
Pro Dark theme improved!
Cons
Con Slow & Buggy (on Mac)
Visual Studio can get very slow on Mac... this is partly due to bad UI framework used - GTK. Also, quite buggy and too often have to Force Quit and restart.
Con Professional pricing is a bit steep
The professional edition's pricing is endearing since it costs more than IntelliJ, however, you wouldn't need that if you're not developing for a enterprise.
Con No Linux version
Con Mac version sub-par
The Mac version has the same great Roslyn editor as Win and VS for Code.
Con Too much storage eater for low-end PCs
For a particular task, you need to install workspaces. Workspaces mainly take up to 50 GB.
Con Branding & online website is super cluttered
There are lots of official home pages for this IDE, the packages, and the repos - hard to find correct one. Also, the main name in IDE: "Eclipse", is same as "Eclipse Foundation" which makes things more confusing.
Con UI can be confusing
There's an overly abundant presence of menus, this forces you to constantly click around the different menu structures; foreign ideas, like Views and Perspectives; strange menu choices, like configure settings located in Windows menu->Preferences.
Con Lack of plugins with good user interfaces
Many Eclipse plugins are extremely confusing, with UIs that are even less consistent than Eclipse itself.
Con Plugins can be unstable
Though there are plenty of plugins to choose from, they aren't always reliable. Some aren't maintained, bug fixes can be slow, and you may need to download plugins from multiple sources.
Con Tends to be slow and lags a lot
Con Poor language support via plugins
Eclipse supports other languages with a huge amount of plugins. Many languages have their own distribution, but multi-language is hard to exist in one project. Like Scala, there is no official support from Eclipse for this language. If Eclipse gets an update, languages such as these will not.
Con Newer versions are getting less stable
Eclipse 4 Neon randomly hangs. For example, during installing new software.

Con Some old bugs don't get fixed
E.g. change a parameter name to the same as a field - the field will not be prefixed with "this." like in IDEA.
