Say more - I agree but curious why you think this. I think the BART trains feel way cleaner (the newest MTA trains are clean but the rest feel old / grimy - which is a vibe but not one everyone likes)

Honestly I forget what I was thinking when I wrote this, but probably just that there are many more stations near where I would want to be and that they seem to run more frequently. Also the thing where you can just use your credit card is very convenient as a visitor.
