Which of the live flight tracking portals are accurate?

With frequent travellers in the family, I keep track of their flights on Google and FlightAware. There are others as well.

Some of the flights are shown with different departure times and arrival times. Do these portals declare departure as from Gate or taking off; and arrivals as from landing or arrival at Gate? Which do you use and found to be more reliable?

FlightAware does seem pretty reliable, I just wish it would give times from DC to DO (because if you are tracking efficiency, you want to know just how much time gets wasted with push backs, waiting for slot, taxiing and such) however its TO/TD times (which are the times it gives) are spot on (and you sort of know the reason why it's TO/TD times - it's that's what the ATC system logs). Would be nice if FlightAware put tail number in logs - right now I switch between FlightAware and FlightRadar24.

I switch between PlaneFinder and FlightRadar24. the former seems more reliable,but FR24 has more features.

I have FR24 on my Samsung phone which has tracking in real time (cost US1.99) which displays the height & speed of the flight at any point.

The 3D version displays the altimeter however that option will use a lot of battery. You can also set alerts eg when a particular flight is at less than 10,000 feet for example.

I actually contribute to FR24 using a ADSB receiver and feed raw info via Internet to their servers. So long as the aircraft has the ability to fly in RVSM airspace then it will have good flight tracking that is close to spot on real time.
