Which Wiki-ware wins?

Wikipanion Plus is the most feature-rich and best-designed Wiki search app of the bunch; it is also the most expensive by a large margin. If you find yourself constantly using Wikipedia on your iPhone, then Wikipanion Plus is the app for you. If, however, you only turn Wikipedia occasionally, want the answer quickly (perhaps to settle bar bets), and don’t care about frills in the least, I would suggest WikiPDA. If you fall somewhere in the middle, as I suspect most people do, Look Up: Encyclopedia for Your Pocket is a great compromise between feature set and design.

All three apps are compatible with any iPhone or iPod touch running the iPhone 2.x software update.
