Still, I gave Jisho a go, and presentation-wise, it does come across very nicely - DMG format for distribution with a pretty folder background image, all Cocoa, etc. The fact that it uses the JMDict file is a boon as it readily makes for multilingual lookups. But - and it pains me to say this - it is bloody slow. JEDict is consistently faster, even when searching through the enormous Monash name dictionary (details here). JEDict also features a very impressive radical/component-based lookup.

Whilst JEDict does very much reek of Carbon, of which I have never been much of a fan, it is - as it stands - by far the more comprehensive tool. That said, I will be watching Jisho’s development with a certain keenness - I’d like very much to see what it grows into.
