Call recorder recommendation?

I'm looking for a good call recording app. I've tried a few, but so far none is ideal. Instead of trying them all (there are lots) I thought I'd ask on a couple of forums first.

Here are the features I'd like to have:
• Good sound quality (of course)
• Small files, with selectable format (mp3, amr, etc.)
• Automatic sync with clous storage (Google Drive, etc.)
• Import call recordings from other apps
• Configurable location for recordings
• Editing capability
• File renaming...
