I highly recommend trying out iTerm2. It's very similar to the native Terminal application that comes with Mac OSX, but it has some nice features that can accelerate your workflow, making you more productive.
While you're at it, you might want to consider installing Oh My Zsh as well. It is a tiny framework for managing your ZSH configuration. It basically enhances your terminal by providing you with handy plugins, themes and nice tools. From their Github Repository:
Oh My Zsh is a way of life! Once installed, your terminal prompt will become the talk of the town or your money back! Each time you interact with your command prompt, you'll be able to take advantage of the hundreds of bundled plugins and pretty themes. Strangers will come up to you in cafés and ask you, "that is amazing. are you some sort of genius?" Finally, you'll begin to get the sort of attention that you always felt that you deserved. ...or maybe you'll just use the time that you saved to start flossing more often.
The combination of iTerm2 and Oh My Zsh is very nice. I use it on a daily basis and I recommend you to try it out yourself!
