I use the moultrie D40 and D50. Both models are very similiar and almost exact. I have a few of both. I have had great success with them and they get the job done. I believe they are excellent for the price. I cant speak for anything else though because this is all that I have used. Over bait or minerals, they work terrific. When using on a trail, I put the camera on the trail so the deer is either walking into it or walking away from it. No worry about trigger speed that way. Using 6 cameras, it's nice to run the same brand and models. I recently purchased rechargeable Tenergy batteries this year also. Expensive up front, but running the cams year round, they have already saved me a lot of money.
