Depends on the bike for me. On my road bikes and gravel bike, I'm all about my 2x11s. I'm running compacts with 11-34 cassettes on most of my road bikes and the gravel bike has a 48/31 with cassettes ranging from 11-28 to 11-40, depending on the event I'm doing. I live in the mountains, we have some big climbs, and the 1:1 low ratio is fine on my road bikes...although I am a XC/gravel racer, so I come at it from that perspective and with that sort of fitness.
On my mountain bikes, I am so glad we are in the age of the 1x12...I hated the old bikes with the triples. I started out racing XC on a triple, just as 1x was starting to catch on. I know how to shift and adjust a derailleur, but I had a few instances where a downshift and some harsh bumps would lead to inopportune chain suck. Not to mention that I was constantly busy with shifting.
My next XC bike was a 1x11 and now I've replaced that one with a bike w/ 1x12 with wireless shifting. If there are any gaps in gears, I don't notice them riding off-road. My tallest gear is a 40x10 and does just fine on a wide-open descent. The 50t cog is good enough for a walking pace on climbs. For racing scenarios and even spirited trail riding, the wireless is a nice feature. More specifically, the ability to shift 3 gears with one push of the shifter...makes it handy for when you're descending, but suddenly come across a turn or steep rise.
My longer travel "Enduro" bike has a 1x12 as well, but with a front ring geared for climbing on a 35lb bike with inefficient downhill tires. You can spin it out on a paved downhill, but pavement is not the mission of that bike.
