If you like CTags give CScope a try. It's sort of like CTags on steriods. Also Vim can work with a combination of both (it loads both cTAGS and cscope.in) so you don't loose any functionality. The biggest plus you get when using CScope is the ability to do a "reference" search. You can find all references to a given symbol in your project quickly and easily which I find invaluable for refactoring (what's going to be affected when I change this?).
