I own both. I prefer the scrapper 6. I like the feel of resiprene C and Scrapyard is the only company using it. Micarta is a dime a dozen these days. Some other adventages of Scrapper is a longer handle and extended guard which btw is almost non existant on the Ranger RD knives. If a knife is designed for hard use, it better be safe to use too.

Just my 2 cents.
