Maybe it's a bad choice for you... that's fair, it seems to be a great option for me. I will likely never ride a TT bike with 2 rings in the front ever again.
That's it, its a very personal thing as to whether you like 1x or not. I've been running a 1x setup on my TT bike for around 8 years and will never go back to 2x. It's not for everyone (some people "must" have tighter cog spacing that 2x provides), but I never notice bigger cog jumps / cadence changes, or it just doesn't bother me at all.
Before moving to Etap AXS 12sp, I ran 1x11sp with a 54T x 11-32T.
With AXS, I started with 50T x 10-33, but recently changed to a 52T chainring. I found with the 50T, although technically the 50x10 is a equivalent to a 55x11, I just felt like I couldn't hold power on descents, so moved to a 52 and happy with it. I am naturally a lower cadence guy, so really prefer holding power at 70-80rpm on descents as opposed to spinning at 100+. The 52x33 is enough gear for where I train and probably 99% of the races I'll ever do.
Oh, and all those naysayers who complain about "excess friction" with 1x chain lines at the extreme ends of the cassette, you spend so little time there it probably makes zero difference in real life. And they conveniently forget that the time spent in a smaller chainring is at a higher chain friction than a big chain ring... something you don't get with 1x!
