If you're chasing Strava KOMs or riding with an "un-paced" group, then you'll be at a disadvantage with 1x. Likewise if you're doing hilly stuff, getting the range you need will open up big gaps in the gears. But solo or a paced group in the flats can be very comfortable on a 1x.
I rode my CX bike (38t x 11-26) yesterday with a 24 MPH paced group on a totally flat route and had a great ride. However, if the CX was my only bike, I'd probably switch it over to a 36/46 CX double just for the added flexibility.
Switching chainrings on a 2x or 3x is a simple matter of shifting. No cassette swaps ever needed.
No disadvantage to the 3x setup on my bike. No rub in any gear combo , big big, or even small small.
The stigma of a triple means nothing to me, nor does the status of a 1x.
