There's also Turtl that's similar to Evernote—but it uses Markdown for formatting, so also can't say anything about it.
On my part, I came to prefer my own written notes over clipped content and media, and IMO an outliner is way better than anything else for organization of such notes, specifically when keyboard shortcuts are good. Alas the competition is thin in this space: I used Workflowy for a while, which worked great for text and shown promise, but was stuck feature-wise after a couple years. Aside from Workflowy, it's pretty much Org-mode or OmniOutliner. Gotta say I do miss page-clipping from Evernote, and would be happy to see something good in this vein for Emacs/Org.
