Same, though the fact that you don’t have to connect to the T helps a lot. I was going to Kendall Square, and it was reliably 2 hours or more each way thanks to the red line.

One other thing to keep in mind is that parking at PVD station is now $18 a day and is a super small lot… but there’s a surface lot next to the Citizen’s/Cafe Nuovo building that’s always available, costs the same, and is a 3 minute walk to the station. Parking availability shouldn’t be a concern (though cost certainly could be).
