It’s the same rifle. Remington bought the equipment and patents from Marlin which Ruger acquired from them in the sale.
Only difference would be if the fit and finish changes because of poor quality control (like the early Remington rifles did because all the employees were either new and inexperienced or former Marlin employees and potentially disgruntled).
I owned one of the late Remington rifles (after 2018) and IMO they were as good or better in quality than the JM stamped rifles.
Ruger has made quality control their top priority thus, if true, they would also be as good or better in quality than the JM stamped rifles. Obviously we will find out for ourselves when they arrive later this year.
