I was hesitant to go the “shatter proof” bulb route this year because they tend to look cheap but they were hard to avoid. These are the best I’ve seen. They look real and don’t have a plastic seam running down the middle. I tried to get a good photo to show they are reflective like a glass ball would be (not exactly but good enough). 
I purchased others at Target and they look cheap. 
I would buy again.
