I will jump into this discussion. I use Campy Ergo on my road bikes and Sram on my gravel bike. The ergonomics of the hoods are very close. However, the Sram sweep style shifting vs the Campy brifter and thumb button are completely different and when I am on the gravel bike, I invariably miss shifts and find that I miss the Campy down shift motion and up shift motion of multiple gears at the same time, etc. So yea, you do naturally adapt but it is not the same... Personally I have never liked the Shimano big lever / small lever design. My wife has Ultegra 10 speed on her road bike and when I take it out for a test ride after some work on the bike, I have to wonder why so many people like this setup. Slower to shift, not as clean feeling, and well, dare I say - sloppy design.
