Mainly Flipboard as it's a decently curated list for my needs. Also playing around with Newsify, but haven't really used it much as of yet. Probably going to cancel my Feedbin subscription as I just don't keep up with it. Used to use Unread or Mr. Reader with it. And like everyone else, Twitter (via Twitterific, at least until Tweetbot for iPad is updated (if it ever gets there)) for "breaking news."
Newsify for my RSS feeds. I used Feedly for months but when they had their issue a few months back with their server being hacked or whatever, I tried Newsify and never went back. Also I use Pocket as a companion app so that I can send articles there to be read later if it's something that'll take too long. Never been crazy about Flipboard for two reasons...1) the layout takes too long for me to flip through everything. 2) there are a few of my RSS feeds that aren't supported on Flipboard.
I use Feedly works way better than Flipboard, I heard good things about Newsify going to try that soon. Oh and I also use Tweetings 2, in my opinion the best Twitter app, yes even better than Tweetbot.
