Laminar's website is but one point of reference . The OP is entitled to canvas opinions from others who use P3D for training purposes, whatever they maybe . Not unexpectedly, the LM website promotes it's products virtues not so much its weaknesses.
In my opinion OP, P3D is not great as an IFR trainer ,as an example, no matter what the website says.
Reason; the ability to reproduce side view traces of the flight path to determine how well an approach was made , how altitude was maintained what the trace of the holding pattern looks like are not as well done as Xplane.
OP keep asking your questions , someone sooner or later will have the good grace to reply with a useful answer.
