Poser, even by Daz's rather slow standards, got left behind by the rest of the industry. It's probably at a point where it's not worth learning. If you dislike Daz, you'd just be better off staying with KK and HS 1/2 - the latter of which you can get some pretty surprising results out of. But the reality is that Daz isn't easy to learn. It's the UI, then it's figuring out assets and posing/expressions, then it's lighting, then it's skin and textures, and so forth. 3D, even with Daz being easier than the rest, isn't something that you can just pick right up.
You have to put some work into it, and even more so, want to do it.
