Thanks Boomer... Although it doesn't look like the TrafficX aircraft are much "better" than MyTrafficX, MTX is still primarily populated by FS9-format AI, while according to JustFlight, TrafficX is entirely FSX native. I don't have the latter to confirm one way or the other, but do have the latest-but-one version of MTX, currently uninstalled.
Seeing as both are mentioned in numerous places on this thread, evidently there's some confusion here about which product is which! Just out of interest, can anyone who has TrafficX (i.e. the JustFlight version) tell me whether it randomises flightplans in the same way that MyTrafficX does, or whether it uses real-world-ish schedules?
In case anyone doesn't know, MTX doesn't use hand-coded flightplans. It takes a series of rules (e.g. a UAL aircraft will be based at specific places in the US, while an AFR aircraft will be based at specific places in France, BAW aircraft in the UK, etc.) and the rest is totally random. You can specify flights if you want a specific sector to happen, such as, say, twice daily Concorde flights from Heathrow to New York, but the schedules are not real. If you have default MTX installed and go to Belfast Aldergrove (EGAA), as an example, it is heaving with Ryanair and British Airways aircraft. In the real world, neither airline operates to or from the airport.
That won't bother a lot of people, but it will others, so it's worth knowing.
