I thought I'd just watch this and stay out of it, but . . .
The information in MikePA's first post is probably the best information. You
always have a better chance (doesn't mean you'll win) if you have a lawyer go to court with you. Judges are lawyers and they want to see you help to support the profession financially.
Now for a few things I've seen personally.
Beware of lawyers who say you don't need to go to court; that they'll take care of it. Sometimes they just don't do anything at all and you won't know it until you get arrested for failing to appear. Or, of course, they actually may take care of it. They may be bribing someone in the court to get tickets dismissed.
If you hire a lawyer, be sure you pay with a check or get a receipt. I've booked lots of folks into jail for failing to appear who said they paid a lawyer and thought it was taken care of. I always asked if they paid cash or check and whether they got a receipt. It was always cash and no receipt, of course. I'm sure some lied, but I'm also confident that some didn't.
Without a lawyer, you can get into as much trouble with a judge by talking too much as you can by not stating your side. He's not interested in what a fine a fellow you are; family man, employed, never arrested, go to church, etc. that has nothing to do with the current alleged violation.
A lawyer will probably have some knowledge of the court's honesty, or lack thereof, that you won't know about. In 1972, at the National Safety Council meeting in Chicago, there was a panel discussion that included a police chief, driver instructor, and a judge. A question arose as to how to "beat" a ticket in court and the police chief said it was simple; hire a lawyer and your ticket will be dismissed. The judge was obviously annoyed, but admitted it was true. She said if you had paid a lawyer, she felt that you'd been punished enough, so she dismissed all those tickets. I always thought fines went to the government agency, not to lawyers. Well, a short time later, I had occasion to meet the chief administrative Cook County traffic court judge in a class he was supposed to teach. So, being a naive southern boy who thought that female judge was crooked and I'd stool her off, I asked him about it. Well, come to find out, he was even worse. He dismissed all tickets if the recipient came to court and plead not guilty. He
claimed his theory was that if a person took the time to come to court, that person really believed himself to be innocent and by dismissing the ticket he'd feel he was treated fairly and it was good public relations for both police and courts.

Of course, the local police officers disagreed but had to be careful what they said in front of their judge.
