Each to their own really, I just find XNALara really awkward myself, hence why I barely use it. Daz3d is a free rendering program and I personally find the interface is a lot easier to use and the models easier to pose and place, you can basically download or buy models for it. In a sense, think of it as a great big create a wrestler kind of program in terms of compiling characters using items and what not. Like with XNALara you can make some very solid rendered images from it, but it does not have the benefit as I said earlier of being able to use per-rendered characters from games. (I think I lie actually, there is a way to port them in but I hear its a helluva complex and complicated and basically not really worth doing.) Hence when Mila comes out from DOA 5 on XNALara I will probably just have to sit and wait patiently for some of the guys here to make some awesome renders of her. (Preferably in bearhugs or bodyscissors XD)
I have some renders on this site of my character Jetta who was made and rendered in Daz3d if you have a nose in the image section of the forum. Being a big fan of waist constriction you'll find bearhugs and the like in there. I also have an image lying around somewhere of Tyris Flare in a bearhug from Goro that I made using XNALara, it took me a lot longer to make than it did any of my other images in Daz3d, hence my preference for the latter.
