I have pretty much tried all of the 'holy' trinity of Font Managers (Yea, I'm not counting Apple's built-in FB): FAP, SF, FEP - I was amazed at Font Agent's Pro ability to keep up with our maddening pace of fonts and suitcases until Snow Leopard - after this, there that FontExplorer has been pretty much leading the way in our stability day-to-day work. Still a little bit buggy but offering really nice features. Fonts turn on when they are supposed to, Apps don't lock out, etc... Now, with 2.5.1 if Linotype could only fix the issue of the main program automatically launching the moment one of the CS5 apps 'requests' a font, we would be much happier. If anyone has a fix for this, please let me know. Otherwise, still not a total 10 in my book.
