I used both extensively and both are great—the Recoil actually had more distance for me, but both got stupid hot. The main difference is the handle on the NRG is noticeably thinner (and the barrel is longer), so that is just a matter of personal preference as to which you like.
They both have a 14.5" barrel. Don't believe everything you read in here. Too many miken gurus. I liked the Recoil better. NRG felt stiff and the recoil ended up feeling softer IMO.
Keep in mind that both bats have original versions and re-issued versions. Original versions of both last much much longer but take a lot longer to break in while the re-issued versions don't last nearly as long but break in fast. Re-issued versions can be spotted with serial #'s that start with a 0
