I think most of these apps make for great screenshots, but I'm less sure about long term, daily usability. In my (very personal, subjective) opinion I find that apps that use standard widgets make a less exciting first impression but are usually a lot more usable. The best example I can think of offhand would be Twitteriffic vs. Tweetie.
