Have you seen a Maryland MARC train? 800 people on each train coming into union station in DC every 20 minutes. It’s by far the best way to commute into DC. SAME goes for the VRE in Virginia and Amtrak for intercity.

It’s by far the best way to commute into DC IF and ONLY if you're planning to spend all day in DC on a normal work day. But for that segment (which is huge), MARC is great.
