Been reading this thread and have been testing out all the possible apps to use myself. I've tried TripCase and Worldmate as well, and while they seem to be more versatile I found the interface to be far too clunky and non-intuitive for my tastes. Worldmate also failed to extract 3 out of the 4 confirmation emails I've sent it, so it doesn't really work as a time saver.
In the end I'm finding TripTracker to be very aesthetically pleasing to use, and like the fact that it imports details from my TripIt account. So while I use TripIt to aggregate my travel data, I actually use TripTracker to read through my itinerary. I'm also testing out FlightTrack and Flight Update, but I'm torn as to what I should stick with.
TripIt seems to provide a good platform for these apps though, and using TripIt Pro might add even more to that, but I don't know. I wish someone would just make an all in one app and be done with it.
