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 @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.
