If you feel that you can afford it, you should definitely give it a try.
The major distinction between DW:U and other 4X games is the scope really.
It really feels like a living galaxy.
It's real-time but pausable (Like Stardrive).
You can put any part of the game from ship design to diplomacy to colonization on automatic.
You can even focus on controlling just one ship (or none) and let the AI deal with the rest.
Every race has different goals, tech, planet habitations, stance, ships and traits.
Spacesector has a good review Here.
For reference, my favorite 4X games are;
Sword of the Stars, Space Empire IV, Master of Orion III (yes, 3..), Distant Worlds: Universe and Imperium Galactica 2.
Endless space and Armada 2526 Supernova are fun but lack that something.
I've played almost all 4X games out there. ,)
You could also wait for Predestination, M.O.R.E or Stardrive 2 to come out.
