After 2 very bad experiences with connections on Delta this summer and their total lack of help solving the problems, we will never fly Delta again. Even if they are the cheapest, we won't take them. Spent an entire day (16 hours) stranded in the LA airport, while our flight was delayed first for mechanical problems, then personnel problems, finally to fly out on the red eye (2 hours late also), to arrive in Atlanta just after they closed the doors on our connection, and spent 8 hours in the Atlanta airport on standby. They did not care in the slightest, we were not even offered a meal for our family's trouble.
Had to fly them to Seattle 2 weeks later, and numerous delays again, arriving 8 hours late. We got on planes, only to have to get back off, flights were mysteriously cancelled, it was awful.
If you have a direct flight with no connections, you might be better off.
