Sorry, but with enough polygons in the head any figure can look like any other figure.

Attached is a very quick and shoddy Poser "Simon" morph I made for my weightmapped David 3.

It was really just playying around with the morphbrush for 5 minutes.

So if you think all DAZ characters "look the same", the problem is with the people making the morphs, not the figure.

Making a "Simon" or "Rex" clone for Genesis-2 is just as easy as making a Michael 3 or Michael 4 clone is.

And if you use a "Simon for Genesis" clone instead of actual "Simon", you can have the "look" you prefer but still have all the better bending and more efficient meshand instant cloth and texture compatibility of Genesis-2.
