Your Kittens are adorable
Wet is definately best - I feed my senior grrl the Wellness canned, a couple of different varieties to give her something different every couple of days & I am adding water to it because she has kidney failure but it is a great idea to start when they are young. Cats are great @ conserving water so often drink very little from the bowl so adding to the wet ensures they are receiving this vital nutrient
plus it won't dry out so fast
Leaving a bowl of dry krunchies out for snacking is also a good idea as cats are grazers/nibblers who will go back to the food several times a day.
