Con Rarely updated
Con Nonexport and support desk say they will never include it (your data is theirs now)
Con Support non existing
Con Offline sometimes
Con Subscription based
While not expensive, it does cost money to get it for Mac or Windows (although you can view it in the browser for free). The subscription also adds automatic cloud sync, sync with Google calendar, adding tasks via email, manual sort, attaching Evernote into tasks, and more.
The subscription costs $2/month, or $20/year which is very reasonable
Con Sometimes it doesn't see your active subscription
Con Not very customizable
There is no way for you to create your own "perspective".
