Ross has a relevant science degree and seems to require fewer miracles than YECs. His sort of OEC belief falls well short of theisic evolutionism.
I don't know much about Ham specifically other than seeming to remember that is is one of the "you weren't there so what do you know" crowd.
I find it interesting that the Trinity Broadcasting Network has two shows about creation. One is the YEC Carl Baugh's production in three good time slots. Ross has one show that plays at 4:30 in the morning. The conservatives at TBN seem to favor the YEC view.
Ross is interesting and shows an astronomical argument against a 6000 yr world, but he still balks at faunal succession and requires a few 'stocking' miracles now and again. I don't remember his version of geology. Some of his biology seems stretched but he beats the YECers in science hands down.
