pyvim vs Qt Creator
When comparing pyvim 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 19th while pyvim is ranked 67th. 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.
Specs
Ranked in these QuestionsQuestion Ranking
Pros

Pro Fast development of new features
Pyvim is written in Python. It's a great language that allows for fast development of features and quick bugfixing.
It also relies on existing Python plugins to add even more functionality.

Pro Vim-like editor
Pyvim has some of Vim's features and shortcuts, as well as some custom improvements that are already built-in.
Pro Great syntax highlighting and auto-completion
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.
Pro Integrates well with non-IDE workflows
Qt Creator uses normal .pro-files, CMakeLists.txt, Makefiles.am, etc. for its projects and rarely needs special configuration for projects.
Projects can be built on the command line as usual.
Pro Built-in Qt GUI editor
Allows for the creation of a window based UI in a graphical editor, no code required to build the UI.
Pro Fast and fully keyboard-navigatable
Responsive UI, no need to use the mouse for the power users.
Pro Supports CMake
Pro Very responsive when compared to similar software
Pro Much space dedicated to the code
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.
Cons
Con CLI only
Pyvim runs through the terminal only.
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).
