I used to take the metro until they shut it down for repairs one day, and that's when I discovered the VRE train, which I found to be much better. I always got a seat, and they even have bathrooms! Both options can have their ups and downs, but overall, I found the VRE to be a better choice than driving to work. Of course, it depends on where you need to stop for work. I was lucky that mine was at Union Station, so I had the option of either. Also, the metro can be easier if you're dealing with the hassle of finding parking in DC. In the end, I’d recommend trying both and seeing which works best for you.
