They are owned by different companies, which can be confusing. Luckily, they all accepted the same payment card (which, surprise surprise, was better than the crappy metro cards), and they all connected, so it didn't really matter.
It was a bit more expensive, but not much-I think we generally paid around $2.40 per ride. They do have zone based metering, so if you lived further out, that may be true.
