It has been a while since I landed on Digg but I tried quite a few web based apps including Feedly, The Old Reader and several more that have already shut down. I also tried a few native tools like Safari's built in reader and Reeder on MacOS.
At the end of the day, nothing has been as good as Google Reader... at least not for the way I want to use it.
I feel your pain on loosing Google Reader. I have tried dozens of replacements and finally landed at https://digg.com/reader if you can believe that... Also, I am sure you have seen them but just incase you haven't - https://theoldreader.com/home was super similar to Google Reader.
Alas neither of these are the same but perhaps they will be "good enough".
