Mandrel vs crush bend; Worth it?

I would have to think that the guys that buy the mandrel bent exhaust systems off venders like tti, etc..... are wanting a OEM system, or that pretty look of the mandrel system, or just don' t have a local shop that can do it. on these A bodies, the bends can be pretty tight and hard to do. I had to look for a different guy to do my exh on the 273 65 cuda. the guy that usually does it didn't want to fool with it. can't blame him, he;s 70, the weather if hot, he doesn't need the $$, and it is tight bending!
