Shimano likes cup and cones because the manufacturing tolerances are quite large and they are easy and very cheap to make. However, the cup and cone friction is higher than on high quality industrial cartridge bearings like SKF or NTN. I do not miss the maintenance on my old Campy cup and cone hub, BB, or pedal bearings. The only lousy experience? Trek's stupid glued in BB. Pretty much all my cranks have 24 mm width and BSA threaded BB.
I do like my triple on my loaded tourer and never in a million years thought I would ride anything but 2x on a road bike for many reasons.
I actually have a 1x crank coming today. 48T to pair with SRAM 12 speed AXS etap. 11, 12, 13, 14, 15, 17, 19, 21, 24, 28, 33, 39 to replace 53/39 and 11-32 11 speed that I usually randonneur on. I am giving up the 126 inch 53x11 for a top gear of 115 inches or 48 x 11 with the benefit of more appropriate 1 tooth spacing down to 84 inches. My normal cadence is only 70 rpm at rando speeds, so, the 13T, 14T, and 15T are good cruising gears on the flats for me. My 48x39 is identical to the 39x32 at 32 inches. Whether the low gear of 32 inches is sufficient is the big question but I am not adverse to walking very steep hills. I am sure Campy's 13 speed would give me everything I need.
