I bought the Kodiak screen house, very similar to springbars
I don't think the clam style shelters are a good choice because the screens do not open and there is only one door. So if you wish to use it as a canopy there will be very little, if any, breeze that comes thru. With that being said the Kodiak/Springbar screenhouse is not a great canopy either because the ceiling is not very high so when you stand in it the area around your head gets kind of hotboxed due to the shape on days with no or little wind. Also, the canopies on each side are not tall enough to stand under, at least for me and I'm 5ft 8in, the canvas will touch my head. I still think they are the better choice if you factor that they don't require guide lines to trip over and should be stronger in the wind. I also wanted to be able to use the screenhouse as a tent and the Kodiak/springbar style works great for that.
I've heard bad stories about the clam style collapsing in a good wind.
A EZup canopy with screen wall attachments may be a good option as well.
