Thought on episiotomies?

Hello, ladies! 
I have a question for some experienced mommies! I've Googled but everything I've read hasn't helped much! 
Did you have an episiotomy with your first? Did it help reduce the chance of tearing or did it only cause you to tear more? Or did you just chance it? If so, how did that work out and how bad would you say tearing naturally felt? If you've ever had both, which would you say was easier to heal from?
Thanks in advance for everyone that answers, as a FTM, I really want to try to prepare myself for everything possible - good and bad. 🙃
