It entirely depends on your use case for the monitor/TV. VA has superior blacks, but worse colour accuracy and is prone to blur and overshoot in gaming. The viewing angles are also inferior, which on a big screen can sometimes even be evident even sat in front of it, with visible gamma/colour shift.
For TV content, due to the superior blacks, VA is often preferable (although the viewing angles can be an issue if you have people sat at sharp angles), and from a visual point of view, gaming on a VA TV/monitor often LOOKS better, but the moment you get heavy blur/overshoot, it ruins the experience.
With IPS however, monitors are often more prone to bleed and glow, which in bad examples can also be very annoying when watching dark content in a dimly lit room. VA does not suffer from this anywhere near as badly... there is no glow with VA, but it can still suffer from some backlight bleed.
For professional colour accurate work, IPS is the only option.
