In my opinion, C++17 makes real progress towards compact, expressive and easy to read code.
One of the best things is constexpr if that allows you to write template/metaprogramming code in a similar way to standard code. For me, it's a huge benefit (as I am always frightened of those scary template tricks).
The second feature: structured bindings (that works even in for loops) feels like code from dynamic languages (like Python).
As you can see all of the mentioned features are already implemented in GCC and Clang. If you work with the recent versions of those compilers you can immediately experiment with C++17. Soon, a lot of those features will be available in VS: VS 2017.3
