You mean the bridge? Personally, I like the Zotac bridge. Simple and tasteful.
The problem with all these bridges, though, is they look off when it's mismatched to the brand of your cards. I'd stick with the bridge from whoever makes your cards. Otherwise, I think I've seen posts on the EVGA forums of people 3D printing new covers. You just have to be careful with disassembly if you go that route.
