You mean WMATA?

Having grew up in Boston and spent most of my live there before moving here, WMATA is much better than the MBTA by a long shot.

The system is cleaner, goes much further out to the suburbs and the buses arrive on time for the most part.

MBTA suffers from being built a long time ago. There's too much deferred maintenance, and it's really impacted the quality and usability of the system over the past ten years. Perhaps WMATA might eventually suffer from that too but I hope they keep up with the maintenance.
