Power steering pumps which style is better?

Need a V8 power steering pump pulley for my S6 to 360 swap. Is there any advantage of the Saginaw or the Federal? I know I searched a local salvage yard and the Saginaws are everywhere but not one Federal this trip. My old S6 pump is a Federal but I have to buy new hoses anyway so is the Saginaw the better option due to availability?
