Don't have any experience with the Rem but do have a couple Scouts (the first one was destined to be a teaching aid for my nieces and nephews but was too pretty for that job and kept it for myself and bought another for the job). IMO, the Scout is an exceptional little rifle. On my (then) 8 yo nephew's first time out at the range, he had a couple 5 round groups under an inch at 25 yds (scoped). Not the best the gun can do as I've shot it before to zero it in and had done better but, IMO, a good show for the newbie. The bolt will be a little rough at first but will smooth out. The CZ guns are dry fire safe so you can do dry fire drills before shooting to to give the new shooter a good feel for the trigger without firing.
My 7 yo niece, however, didn't fair as well on her first time out as she's having the cross dominant eye problem at this time.
