I will give you a laugh here but it is true, just as I was beginning to FULLY depend on Evernote (and trust me that App is magnificent and super quick), OneNote begun to work for me, I was keeping a daily "experiment" going and trying to force sync it several times a day, it just suddenly became very very good and it has remained stable and reliable for 2 weeks or so, I never fully understood what the issue was except that info was going TO the server ok but NOT from it!?
I have not used Evernote for 2 weeks now and a simple 10 mins of copy and pasting everything into OneNote swapped it all across.
So far so good.
