There is no 1 best monitor, depends on what do you need it for.
Do you wana watch YouTube and movies? Do you wana play games? What kinda games? Do you wana read a lot of text or program stuff? If you wana do all, which is the most important to you ?
About the VA vs IPS.
VA is great for its contrast ratio. So if you wana primarily watch movies or play singleplayer story based games, VA is your buddy. It has a terrible text reading experience tho.
IPS is the true colour king. If you wana read a lot of text, or find yourself in a situation where more than 1 people are looking at your monitor (maybe playing coop games or watching a movie together), then ips is your buddy. IPS is Jack of all trades master of none.
TN for ultra responsiveness like for competitive fps. Even when an ips display markets itself as 240hz, a 240hz TN panel will demolish it
