Which notification filter do you use the most on PeakD.com?

PeakD.com now has a simple filter to divide the notifications you get... which one do you use the most? (Choose up to 2 options)

Edit: Totally forgot REPLIES. We'll assume it's one most people would have selected

As a follow up question (topic of conversation) what would you like to see different about notifications. It's a tricky thing to do notifications what we use was built by SteemIt INC many years ago and hasn't really seen too much development ever since it was created. The Hive account@peak.open team has worked on an open source system that Keychain is using. What would you like to see.

So if you're using a different notifications system please share and tell us what you love about it we are all ears.

As a reminder of what we're talking about here is the layout of the notification system on PeakD.com and the filter in use.
