IMO.
I had a 2019 that I put a 6" RC lift and ride quality seemed to go down hill, it would feel like a shudder and the front bounce to the left going over bumps or pot holes on dirt roads.
Now I have a 2020 with a BDS 6" lift and ride quality is about the same or as close to stock in my opinion, its smooth, no shudder or bounce in the front end going over the same terrain as the 2019 with the RC lift.
the only difference between the 2 trucks are the year & lift kits, everything else I had on the 19 was transferred to the 20. ie: wheels & tires + the accessories that don't effect the suspension or ride quality.
hope this helps with your decision.
regardless on which one you go with if it comes with replacement springs for the rear make sure you transfer the plastic guards off the OEM spring to the new one in the kit or you get (in my experience) a clanging sound from the back going over bumps.
The RC Kit came with blocks and retained the OEM spring but the BDS has a replacement spring.
