Depends, they are pretty highly regarded, but not by me. I like the colt style better, they fit my hands better, are more natural pointers and handle fouling better. That said the Remington is a more advanced design and eigther will work and it all comes down to personal preference.
did you try shooting it? That will answere most of your questions rite there. I find the Remingtons grip area too cramped to comfortably shoot.
Uberti is considered the top maker of replicas, but every cap gun I've got I've had to do something to it to get it to work rite, whether that was just changing nipples or milling a bur out of the hammer slot in the frame. Uberti's as a general rule I've had less trouble out of.
