SCT versus random orbital sander?

Hi everyone,

In the next week or two, I'm going to start sanding body panels to get ready for body repair, primer, filler, paint and all that. I have a pretty good dual action sander but I've seen so much lately about the Eastwood SCT. For those who have used both, which would you recommend and why?

Thanks!
DA only for finish work. The Eastwood strip tool is more for stripping heavy paint, rust, or old bondo from the metal.
