I was going to say "Because you can get a Samsung or LG for a similar price" but saw the JVC's claimed resolution of 1366x768 which is interesting. If true then there is no reason to not get it besides this being a Chinese rebrand (not real JVC) lacking quite a few features with a poor quality remote.
I somewhat doubt that this is the true native resolution though. There have not ever been, or at least for many years, 42/43" 1366x768 plasmas, only 1024x768 and some lower resolutions. And JVC certainly aren't making plasma panels. Further problem is that it's difficult to get decent info on JVC TVs in South Africa, even though again it is claimed by their distributor to be 1366x768 -
