We've talked about this before. Have you Typophile for previous discussions on the matter?
It would help to know what you don't like those utilities, and what platform you are using.

For Mac OS X, use FontDoctor for diagnosis and repair, and FontAgent Pro for central font management, ignoring (but not disabling) the native Apple FontBook, which is good only for the fonts that come loaded in it (most of which have to be disabled so as not to junk up your Quark font menu). Keep all your fonts in a folder on the desktop; check them in FontDoctor while in that folder, then import them into FontAgent Pro from that folder. Don't load any fonts into a "system" folder inside your OSX Library; that's only for system fonts that come with your Mac.
