My experience with Audacity, has not been as stellar as yours, I'm afraid. Like most open source software (think FireFox), there are too many chefs in the kitchen, and no head chef (project manager), to make sure everybody is on the same page. Quality control is non-existent. The software has crashed on me numerous times.
Open source stuff may be fine for the bedroom DJ, but IMHO, is not close to the quality of software designed for a professional, and supported by an extensive group of well paid programmers/tech support and quality control staff.
If you choose to use a known sub-standard product, in a working environment -- you will get out of it, what you paid into it.
I choose to purchase high-quality products, that will last for years, without bug fixes coming out all too often. That's because I am in business, and make a profit off using those products. I use almost all Sony products when it comes to audio and video editing, because I know they work well, and the price is reasonable.
YMMV, depending on the level you are working on
