Audacity will work fine for recording. No reason to get something else, unless your itching to spend some money.
I do most of my work and laptop recording with Sony Sound Forge, but that is mostly because it is the program I learned how to use first and I am familiar with it.
If Audacity existed back then, I may have used it. Sound Forge probably has some advantages. For example I'm not sure you can use Waves plugins with Audacity, but you can with Sound Forge (and they are pretty damn nice, but also pretty damn expensive).
