After two years on new frames with internal cable routing and Campy 12, I got fed up with cable friction issues and moved on to sram force axs. Within a few months, I moved on to disc brake frames and tubeless tires too. No regrets. I rode Campy only for 25 years, but they're now lagging far behind shimano and sram with little electronic shifting.
One good development is that the sprocket spacing on all three brands is very close to the same, so the cassettes are relatively interchangeable with the right freehub body. The axs chain is the most universal. I used it extensively with campy 12 and others have used it with shimano 12.
In July I'll have two years on sram force axs with no problems. I use shimano grx cranks for more range. I've also used Campy 12 cranks with axs.
