It should be noted that some of the features listed here can also be found in the Busy frontend as well, but I mostly use SteemPeak when I'm not experimenting with stuff -- having the stars and resources page a click a way is just so very comfortable.
Though there are complaints as well:
- There's no option to track follows or mentions for the notification feed
- The self-vote option might be set to ON by default (at least it used to be) as it is in Busy
