Is it better to go to court or get a hearing waiver for traffic violations?

I recently got a speeding ticket for going 70 mph in a 55 mph zone. My only other speeding violation was a couple years ago while I was in high school, but I had gone to court for that and received a probation before judgment ruling to get the points expunged from my license by pleading guilty with explanation. However this sounds exactly like getting a hearing waiver except with the possibility of having the cop not show up and getting the case dismissed. So what should I do? and if I do decide to go to court can I still did what I had done before? I know I was speeding and I don't care about getting the fine, I just don't want the points to raise my insurance.
