How many people actually use the command line? Probably, a very small minority.
I don't have any issues with speed or sync.
Good luck trying other software. I've been there. I tried Zoho, upnote, Notesnook, obsidian, etc. Etc. Etc.
Upnote is the closest, but no OCR, mail in notes, and some other stuff.
Evernote simply works the best out of the bunch, even though others have features evernote does not.
Is it perfect...no! But there really isn't anything close to it. It just works.
