edit: Just decided to log in and check ;) So what I didn’t like was the way it popped up from the side instead of actually doing what GReader (and TT-RSS and Newsblur) can do: Simply popping down the current article, and not switching the view.
I am pretty sure that I tried Feedly in the post-"Oh no, Google Reader is going away!" panic everyone else using the service was in at the time, and like you I could not replicate the feel. The Old Reader was the closest alternative I found among the several I tried, but soon afterwards Inoreader appeared with a very, very, very close-to-Google Reader feel, and I've been extremely happy on it ever since. (If only Inoreader would correctly open the comment link and not the original article in the HN RSS feed.)
And 1) I don’t understand. Feedly was one of the first ones I tried, and none of the settings I tried got me close to a headline-only view that I used in GReader. I used Newsblur for a while and am on TT-RSS nowadays. But Feedly always seemed to cater more to those people who enjoy image-heavy subreddits and full-page hero images, or pinterest.
Nothing I tried with Feedly got me a simple, no distraction one-line, click to expand downwards view.
Note that all of this was around when GReader closed, no idea what changed.
