QtCreator and KDevelop news
IMO it should be viceversa.
Qt Creator feels awkward to use, cmake support sucks and is Qt-Centric.
KDevelop can be used successfully when coding STL/Boost only projects. KDevelop also supports other languages than C++ (ruby,java,py,php) KDevelop though lacks qt creator's cross compile support, but unfortunately Qt on nokia devices is dead and i still haven't seen any apps using Qt on android.
just my 2c
And for the news part. Custom buildsystem is being moved to be a core module of KDevelop.
