As an owner of Viotek GN34C that has a 1440x3440 resolution I can say that it is really amazing and a huge upgrade from 1080 and from standard 16:9. It is very easy to open two programs or web pages side by side, without running into all sorts of weird layout issues that you get on a 16:9 monitors. Definitely worth it.
Other than Viotek I can suggest you to look at something like Samsung CF791, Samsung C34J791 or Microboard M340CLZ, as they all have WQHD VA panels manufactured by Samsung and might be cheaper depending on your location, but keep in mind that original Samsung monitors use Quantum Dot technology, which other similar monitors don't have.
You would need a DisplayPort cable to make use of the 100Hz refresh rate, though, or at least HDMI 2.0 to run it at 60Hz.
If you are going to be using it with a modern business laptop you shouldn't see any problem with running programs in WQHD, but it would struggle to run modern games with decent FPS.
