I've tried Eclipse/CDT, Anjuta, Code::Blocks and others. Kdevelop wins for Unix development. Maybe if I had (MUCH) more RAM and my workspace wasn't NFS mounted over a slow pipe I'd like Eclipse a little more. But I was always fighting for resources when that behemoth would run.
What Grey Wolf said, but I like eclipse because it doesn't wait until compile-time to check for syntax errors and warnings... Very useful when you have a large project and can't wait for all of your headers and sources to be compiled.
