I generally tell people that if you want to strike practice Muay Thai, if you want to grapple learn Jiu Jitsu. Jiu Jitsu also covers a lot of wrestling. Arguably Jiu Jitsu is better for real world fights because once you get your hands on someone you can pretty much own them if you're better at jiu jitsu than them. In addition, punching someone in the head can break your hand, so since jiu jitsu relies on chokes and joint locks, you can take your opponent out without injuring yourself. I would recommend just finding the nearest MMA gym near you. Try out the different styles and see which you enjoy most. If you don't enjoy practicing, you won't go to class and you won't strive to improve.
