Post-Microsoft Skype suffers from connection issues, poor call quality, dropped contact lists, impossible to find options, and a user interface designed to be Snapchat.
Calling my mom's phone, which is at the top of my address book, takes like 6 touches, and that's because I do it often enough that muscle memory overrides UI confusion.
Now Skype has gotten even worse (their "Snapchat" UI is completely unusable), and the alternatives have gotten better.
In the last year or two I've found it to be much more reliable, and the reviews seem to concur.

There are lots of anecdotal reports in these threads and in the article, but the objective evidence seems to show that people like it better today than they did in 2012.
