MSFS is relatively cheap
I think that assumption focuses my reasons for not favouring it, nothing to do with snobbery. Within the fATPL training regime (can't comment on sophisticated automation simulations), all things considered, bang for buck the focused training alternatives are in my view so much better. Scroggs views in the interface ergonomics are significant factor in my opinion.
Even the scenery provides enough information to follow a CAA chart if you are so inclided, I'm not specifically recommending it, but it is an observation of mine.
