Having recently upgraded to a Di2 bike from one with 105 and then adding a cross/gravel bike with SRAM Apex, I definitely enjoy electronic shifting much, much more. I also love my deep section wheels, from the appearance and sound they make to some gains in speed (hard to truly say, but the Strava segments at similar power are consistently faster with the deep wheels). All that said... I love my Canyon cross bike, and won my group in a gravel race on Saturday with it. The shifting is not as flawless as Di2 by a long shot - it's not as nice as 105 was either - but the bike works fine, and I love riding it. It has nice, but shallow rim DT Swiss 1850 wheels that certainly didn't slow me down - we easily held 20+ on paved sections of the course. So, yeah, the wheels, electronic shifting and even the PM are luxuries, but I really do enjoy them.
