For me, it very much depends on the kind of diaper I'm wearing. I prefer dry cloth diapers and wet disposable diapers. Of the two, cloth diapers are my favorite. That works out well, as I'll often pin one on for an hour or so, have some fun, and take it off, all without throwing anything in the garbage or having to store or launder wet diapers. It's a very affordable way to go--or not go, I suppose.
(I do, of course, wash my cloth diapers periodically, whether I've wet them or not.)
With disposables, though, I usually don't hold back when nature calls. Not these days, anyway. The squishy feeling of a wet disposable is hard to resist.
All of this sort of figures in my selection of a diaper, too. If I'm in a mood to wet, I'll often go for a disposable. If I'm more just wanting that thick, padded feeling down there, I'll grab the prefolds and pins.

Separately, I wonder if my preference for dry diapers is an artifact of my youth. As a child, I would often take and wear the old cloth baby diapers that were around the house--leftovers from my sister's and my babyhoods--and putting these in the laundry with any regularity would have drawn a lot of attention. So, for years, I would mostly just put these on at bedtime, sleep in them, and stuff them back under my bed in the morning. And
occasionally throw them in the laundry, as my mom did use them for rags and did wash them from time to time.
In my early teens, I began hiking to the supermarket and buying Pampers with my allowance. I'd occasionally wet these, but as it was such a chore to get them and I didn't have much money, I mostly kept them dry too. In fact, I'd often safety-pin little pieces of cut-up underwear elastic to the sides, turning them into pull-ons so that I could easily reuse them.
Might have something to do with it!
