I’m actually pretty sure I just rebent the cut off stock lines by hand and flared the ends. The piece on the bottom is just hardware store sheetmetal, I bent it into a C shape in my vice and painted it white to look factoryish
Which ever fits your application best for routing of lines. Some do have better attachment types for braided lines, etc. mine is more like the lower one and I was able to put it after the radiator and route the hoses well. Sometimes the above type have better mounting solutions or attachment for fans.
For stock to mildly built, either are absolutely fine.
