I think it’s great for that. Probably not for the raw core of flying, but everything that goes on around it - what the dials mean, how the autopilot works, how ADF/DME/VOR work, how to start up would probably save a lot of instructor time.
OP, need more context. Why do you ask this question ? Are you a potential real pilot, or just asking generally.
If you are thinking of buying you can still ‘rent’ it, through XBoxPass (?). This doesn’t give you everything, but gives you easily enough to see what it is like without splashing out.
