Well, I only know VS 6.0 - never felt the need to upgrade. That didn't
have too many toolbars and options. scite-debug has no toolbars,
unfortunately.
I'm developing on VS6 right now (well, as of a few hours ago) --- not my
choice. I'm not sure which is worse; the compiler that's so old that it
doesn't understand 'long long', or the debugger which doesn't have
horizontal scrollbars in the variable view window, which means you can
only read the first few words of any string...
Ooh, wait! No. The thing I dislike most is the 64MB debug info limit per
executable, which means that if you've got a really big project, you
have to start stripping some of your object files to make it link.
I normally develop on Eclipse. But I don't use it as an IDE, I use it as
a super editor and SVN client. Right now I bring it up concurrently with
Visual Studio so I can use it for all the things VS is dire at, like
file management.
