I own both, I have had the shield 9 for a few years and several months ago I bought the SD9VE and put a spring kit and added the Hi Viz front sight, I enjoy shooting it more so than the Shield 9 I have probably because it is a little bigger than the Shield and fits me better. I added a mag extension for a total of 20 rounds, I bought it to have a truck gun and a high cap night stand weapon, but I find that I carry it more now than the Shield.
