Have a toddler who didn't nap but STTN or a napping toddler who wakes up once?

Miss A is gradually starting to STTN on a more consistent basis and slept a whopping-for-her 11.5 hours last night but it was the result of no afternoon nap (fortunately she was quite content to hang out and sing to herself in her cot for 1.5 hours in the afternoon!). I've always coped with the MOTN waking because I could always count on an afternoon nap to last 2 hours so I'm not sure if I like this no napping but sleeping all night thing!

So how about it, which would you prefer?
