I wouldn't recommend any aspiring pilot to use MS FS as an aid to the PPL. Simply because you will get this nasty habit of looking at your instruments rather than on the visual horizon. - That's what VFR is all about. A FS like ELITE is a good aid for an instrument rating, but until then - don't bother! (I know, cause I've been there. Costed me at least 3 or 5 hours of ekstra flight during my PPL training).
Best regards
