I have Global for P3Dv4.
I like it very much because I don't want to spend a lot of time on AI traffic, but I do like to see it in the air and around airports.
I also like that it is some what realistic.
It is easy to install and will install traffic for you all around the world.
You can also add your own without much trouble.
I only have small issues with frame rates when I am flying fast, with lots of airtraffic in the area, and in a complex scenery area like southern California.
Hope this helps
