I use BDS2006(Delphi) and Visual Studio 2005 a lot. The editor in VS is far superior in my opinion to anything else I have used. Having said that, BDS fights back with having a much faster debugging and compiling engine.
BDS is the only IDE that allows C/C++, Pascal(Delphi) and C# from the same IDE and it also compiles Win32 or .NET for Delphi and C++. If you are doing Win32 and are looking at upgrading to .NET in the future, Delphi offers a more or less painless upgrade path - no rewrite is necessarily needed.
It's a pretty impressive result for BDS and highlights again that there is a valid alternative to Visual Studio. Keep up the good work guys!
