Steemworld.org is the only analytic tool I use these days. Exactly, it's "an incredible amount of relevant Steem account data in an incredibly user-friendly layout".

The main advantage for me is that I don't need to register and I immediately see the most important information. For me it's STEEM Power (minnow or whale), reputation and details about voting.

To conclude my post - it's a perfect tool especially for newcomers because you won't lose your time learning something know when you need some quick information.
