I had a Rega table loaned from my friend before I purchased my B&O table, and I did a A/B test today. It's a Rega 25 with Benz Micro MC cartridge. Unfortunately the difference was not subtle. There was more air, more detail, and more clarity using Rega.
However, Rega 25 + Benz Micro combo is probably 4x the price of B&O table.
Also the original cartridge MMC 25CL on my Beogram is 20+ years old. It looks like it's in an excellent condition, the cantilever suspension might have been hardened after long storage.
I'm somewhat disappointed at the result. :( I might try a new cartridge from soundsmith and/or get my MMC 25CL rebuilt.
