Literally no one would ever mention St. Paul if it didn't border Minneapolis. Is this the case with Fort Worth compared to Dallas?
Well I've only stopped in Dallas as an itinerant a few times, but yeah Dallas is a true blue ranked prominent Texas city of importance. Ft worth, while big, simply doesn't stand on it's own by itself in that manner. I mean, just go on google images and look at FW's skyline vs Dallas'.
From what I've heard FW gives off the same vibes as you describe SP up there does. Not a lot going on in terms of entertainment and night life. It's mostly residential. Crime, though, I'm not sure. FW cats tell me all the time that it goes down there more than Dallas.
They might just be talking about certain spots though, like the stop six neighborhood I posted earlier.
