Being a frequent anchor fisherman, I am partial to fluke style slip ring anchors. The are light in weight, hold in quite a variety of bottom content. Yes, they can and probably will get hung on a stump. But that's the beauty of these anchors; all you have to do is to let out about another 1/2 length of line, then do a semi-circle around the hang up with the boat and get up to the up side of the hang. Then just pull it free. The slip ring will accomplish this task each and every time. Have the same anchor I purchased over 10 years ago. I also use a 4' length of chain between the anchor and the rope. Will never go with any other style. Inexpensive too!
