There are advantages and disadvantages with either setup. Being elevated is nice for shot angles and not having to wait on a deer to move from in front/behind of your target deer. On ground blinds you always seem to have a deer in the way. I feed extra corn around each different ground setup on my place so that I can spread the deer out for shot angles.
I like hunting out of both but prefer the ground blind now just so I can be eye level with the deer. A fully enclosed blind is nice to hide movement and help with controlling noise. It has to roomy and tall enough to maneuver for shots though. I mainly have one window only to shoot out of on my setups. I want as dark and as many shadows inside as I can get.
Some of the best bowblinds I have seen in South Texas were done with both setups. One ranch had a permanent elevated box/bow blind at several feeder locations on the ranch. They had some north and some south wind setups. They had them 25 yards from the feeders. No feed pens on this ranch. Another ranch had a short elevated box/bow blind at one end of the feeder pen. The pen was a larger rectangle and the blind at one end for the most dominant winds. IIRC he had both a north and south wind setup.
Another ranch made is own blinds out of concrete remesh, heavy grade black plastic sheeting and brown burlap. He would make a complete egg shape out of remesh that was about 5-6' tall, about 10-12' long by about 5' wide. Only one small hole on one of the narrow ends. He would put the plastic over the remesh and then put cover it with the brown burlap sheeting. They were very simple and he could nest one inside the other to haul them around or store them in the off season. He just set them up at any location he wanted. He would set them about 15-18 yards off the closest edge of an opening or ROW. He would road feed in front of the opening. He had about 20 of these blinds. He preferred ground blinds to elevated stands on his ranch.
Some ranches use 15-18' tower blinds with bow windows in each corner to hunt from. They can stand or sit to shoot out of them since they are made really big inside. Some put them close to corn feeders and others just road feed around them. The road feeding is nice so that you can hunt them blind with many different winds. They still have a corn feeder at a rifle distance, just do not run the feed times very long with a road feeder.
Here is a permanent bowblind and I took the photo from the rifle stand. This is a great southeast wind setup since the wind is blowing in from the SE corner of the blind into the thick brush behind it. It only has one vertical window in the middle of the front to shoot from.
