I would say the first thing for you to do is to try Studio, work with it a little, and see if you like it. If you don't, stick with Poser.

Your Gen 4 Michael and David characters will have to be recreated for Genesis (unless you also buy GenX, that lets you use Gen 4 morphs with Genesis - I can't vouch for how well since I don't have it though).

I am in a slightly similar situation in that I had made a V4 character that I used often and wanted to recreate her with Genesis. I had to turn all the dials again to make the face and body shape I wanted, but it wasn't too hard and since Gen 4 textures work with Genesis, I was able to recreate her pretty well. Then my hard drive crashed last week and now I have to do it yet again, lol.   ;)

But anyway, the real key is going to be if you want to use Studio or not, that will determine whether you can use Genesis (and your Gen 4 stuff) or if you should stay with Poser and what you're familiar with.
