30 year old tub drain leak

It uses an old drum trap. I had 2 plumbers come out and specd the job for removing the drum trap and replacing all drain pipe with PVC and a P-trap in PVC.
However, the local plumbing supply store did not come-up with that solution instead having most of the drain replaced from the tub drain opening up to the drum trap....all in copper.
Which approach is best ? Keeping the drum trap would simplify the job for sure. Otherwise, it would need to be cut-out and a brass threaded coupler would need to be soldered in there.

Most plumbers would replace the drum trap. Drum traps work fine, but need to be manually cleaned out occasionally, which no one ever does. Also, they are no longer code compliant, which gets into a gray area in regards to repairing vs replacing.

I don't see any reason to keep the drum trap unless replacing it would require a lot of floor demolition that you don't need right now. Replace it all with a P-Trap, PVC, and never worry about it again.

Also, copper is rarely used in residential drain systems these days. There's no benefit over PVC.
