Another vote for the Ruger, hands down, between the two. I have had the lefty stainless 243 RAR in both the compact version (which I put a standard length stock on), and the full length version (which I currently have). The accuracy of both was excellent. With the compact, I was getting 2 shots touching at 100 yards, the first day out with it at the range. It is a very handy rifle.
Only drawbacks are somewhat loss of velocity and a significant difference in muzzle blast. The standard barrel almost sounds muted compared to the compact barrel in .243. So, that is something to consider. Like was mentioned, you can get either length stock as a spare part, and switch back and forth with no problems.
I guess if I was setting up a young hunter or woman, I might go with the standard version, and then order a compact stock, if they needed a shorter LOP. Unless there was a particular reason for a shorter barrel, such as in tight blinds or brush
