I haven't ridden a 1x setup, but they're interesting in certain conditions. Especially if rear suspension is in play (^mtb stuff).
My gravel/all road/whatever you want to call it bike has a large 6sp freewheel and triple up front. It's nice being able to get between large jumps in gearing without having to switch across a large number of gears in back. Maybe easier/quicker than having to jump through a handful or two worth of clicks at the rear, though that can be planned for and adapted to.
