In theory, if the steel plates the bolt in cage is bolted to are thick enough to prevent punching through the floor and if the bolted connections on the cage itself don't shear, then it could be just as strong. But welded cages are generally thought of as safer because they eliminate those variables (steel plates still needed of course, but they typically have bigger ones on welded cages). Plus custom cages are a lot closer to the roof line.

Anything more than a half cage on street is a death wish, and I'm afraid Car54 is correct that there is zero data on this important issue.
