PSPad vs Qt Creator
When comparing PSPad vs Qt Creator, the Slant community recommends Qt Creator for most people. In the question“What are the best programming text editors?” Qt Creator is ranked 20th while PSPad is ranked 25th. The most important reason people chose Qt Creator is:
Qt Creator has a code model which basically has the same information as the compiler. So it can do really nice syntax highlighting (e.g. of virtual methods or local variables) as well as provide great code completion.

Projects can be built on the command line as usual.
Pro Very responsive when compared to similar software

Small and beautiful UI, almost all the space is dedicated to the text with hardly and toolbars. Can actually be used on a 1024x768 pixel screen.

Pro Supports CMake
Cons
Con Windows only
It's only available for Windows.

Con No code folding
Does not support code folding.
Con No content assist
Con Poor refactoring
QtCreator has lack of refactoring features. It's not even close to Resharper++ or CLion.

Con Poor multi-window mode support
While multiple windows are supported, many operations will activate in the primary window (debug, goto-line... etc).

Con Qt-focused
Qt Creator is focused on being an IDE for Qt, as a general purpose IDE it performs quite well, but there are areas which are lacking such as project file support (support for generic/CMake projects lags behind Qt projects).
