I use Eclipse and like it quite a lot. The CDT plugin makes the interface much more c++/C friendly and the extensibility of Eclipse with other plugins makes it a "one-stop-shop" IDE for many needs. I use it for PHP, Perl, C++, Database work, and ColdFusion.
One of the best things for Eclipse IMO, is the Mylyn Plugin. Task based filtering has been a wonderful addition to my work flow.
