Drum brake size change

I wound up with 2 drums. The only difference is the NAPA drum is clearly a 2 piece with a huge balancing weight. Well I think it's a balancing weight lol.
The other drum ( Oreillys) is one piece with more machined surface. Im inclined to go with the O'Reilly's at a glance assuming it's been balanced?
Would love some input here
