I would look as to what type of notes do you have? Do you have embedded PDF files that are marked up files. Do you ever search the contents of those files? Do you have a lot of web pages that you have used via the web clipper in your Evernotes notes?
Right now, I am also looking at moving away from Evernote because it seems the company may not be around much longer based on everything I am reading. Or they are going to be raising the price and or cutting even more features based on the latest survey I took from them. There seems to be a lack of direction with the company right now.
I have not found anything yet that handles the notes the way Evernote does or gives me access to those notes from every device I have and use. I know there are some out there, I just haven't found them, or the ones I have found, I did not like as much or were missing some features that I use a lot, day to day actually within Evernote.
