We use Delphi from Embarcadero Technologies:

Pros:

1) Solid, super-fast, single-pass compiler that produces native 32-bit/64-bit executables that can be deployed by copying them to the target machine (single, monolithic .exe with no external dependencies).

2) The language, Object Pascal, is statically-typed, easy to learn, supports procedural/OO/functional coding, and includes modern features like generics, RTTI, and class/record helpers. IOW, you aren't forced to code everything in a class, if you don't want to. The string support, especially the Unicode string support, is also very good.

3) The Visual Component Library (VCL) is still pretty good for creating Windows desktop applications (native, not universal "apps"), and you can skin your application for a different look and feel. Database access is also top-notch, and you have access to a pretty large set of 3rd party components that can be installed into the IDE as first-class residents of the IDE.

4) Development productivity is very high in the IDE, with a WYSIWYG form designer and two-way tools for coding the UI (what you do in the designer is reflected in the code-behind, and vice-versa).

Cons:

1) The price is high, but they're starting to fix that with more special offers and will, hopefully, continue to move the price down.

2) Partly the cause of 1), the product has been mismanaged over the years and its developer base has dwindled accordingly. This was also partly due to the fact that C# grabbed a lot of their market share (as well as the original developers of the product, including Anders Hejlsberg, the architect).

3) The RTL and component library (VCL) need pruning a bit. They've got a lot of legacy code in there due to an almost-maniacal focus on backwards-compatibility.

4) The IDE is a bit schizophrenic and needs to be updated, but it does include just about everything you would need in terms of real-time coding with error highlighting, code-completion, formatting, Git/SubVersion integration, etc.

5) Memory management is deterministic, which makes it very fast, but does require a Create/Free cycle for class instances. An ownership model helps to alleviate this for GUI applications (forms "own" the component class instances that are placed on them). Also, strings and dynamic arrays are reference-counted and managed for you, and you can wrap class instances in interfaces that will allow you to use class instances in a reference-counted manner, also.

In summary, if you simply need something to create desktop applications for Windows now, especially for vertical market software that will be deployed on a lot of machines, then Delphi is a good solution and can be a technical advantage for your company if you know how to use it well. If you're looking for something that you can use to further your job prospects, then it might not be the best solution for you, and you might be better going with .NET/C#. But, be forewarned that application deployment can still be problematic with .NET - the developer edition of SQL Server 2014 refused to install on my development machine this week because the SQL Server .NET-based installer could not cope with something in the .NET installation on my machine.
