I like my two Sram 10 speed mechanical shift bikes, my Campy 8 speed DT bike and my 12 speed Sram AXS Etap bike.They're all fun and all have identical ranges except the AXS bike which is different, but functionally very similar in range. Frankly, I could have easily built up the DT bike with brake/shift levers but I wanted to have a DT bike for the fun of it. It's nice just for that reason alone, variety is fun. And frankly, for my use as an "energetic enthusiast", the 8 speed drive train works as well as the 10 and 12 speeds. The gaps, which are "huge" by modern standards, are functionally irrelevant for me. Shifting is easy and spot on for all 4 of them.
