Archer is good because he's a true reporter in the sense that he's there to fact find, get perspectives from people in and out of the organization and when he editorializes, he has the sense to understand what each side is thinking.
Sturm is downright excellent with his analysis of the actual game, what is really hurting the team, what the strategies each team has employed and the reason behind those strategies. Rafael Vela is similar to Sturm. I don't think Vela's analysis is as strong, but it's not too far away. I think Vela has a better sense of Cowboys history and can write a more appealing article from the sense of not being too long-winded and not having too much filler. However, he does write more from a fanboy perspective. Personally I have no problem with it, but some may not like that.
I think Dan Graziano is decent. He comes off like your typical beat writer for any other team not named the Cowboys. He's definitely pro-Cowboys and does come off like a fanboy. If he weren't in Dallas where the media is filled with hacks that desperately try to make stories and try to include them in stories, he wouldn't be as effective.
Almost all of the rest I find to have no redeemable qualities.
