It really depends on your specific purpose/use of the monitors in question. Here are my thoughts/opinions:
1440p 144Hz TN
The most GPU-hungry among all monitors. Resolution and keeping up with the refresh rate (i.e., 100++ fps) requires a beefy GPU (think GTX 1080 or 1080 Ti). Fast and buttery-smooth refresh rate is ideal for fast-paced gaming (FPS/competitive shooters, racing, and the like). Not noticeable if using for slow/turn-basis games and general workstation applications. TN panels have fast response times, again, ideal for fast games, but, not ideal for professional photo/video editing and movies due to poor color reproduction and poor viewing angles.
1080p 144Hz VA (Curved)
The curve screen slightly adds an "immersion" factor specially on RPG/FPS games. The curve screen is not ideal for programs/applications where horizontal lines are reference points (such as CAD, 3D designs, and even Excel spreadsheets). Some find watching movies on a curved screen a bit off. The 1080p resolution on a 27" screen will have less dense pixel, which means, if the monitor is positioned closer to your vantage point, you may see individual pixels (pixelation). Ideal to be positioned much further away due to low pixel density, but, in turn, decreases the "immesion" factor of the curved screen. VA panel as better viewing angles than the TN panel. Balance of good color reproduction between the TN and the IPS.
1440p 60Hz IPS
The resolution is good for enhancing details in slower-paced games, and with a 60Hz refresh rate, will not necessitate a very powerful GPU as compred to the 1440p/144Hz. The IPS is the best panel type for editing works due to its good viewing angles and color reproduction. Some IPS panels exhibit bleeding along the edge of the screen which might turn viewers off especially on dark scenes. Lower response time compared to the TN panel, so, a lot of professional gamers (FPS) do not prefer IPS as it sacrifices faster input/response over picture/image quality.
