Just some random thoughts on some Poser figures:

M4 and V4 are both fairly decent figures with loads of support. There are numerous textures, morphs and clothing items that work pretty well out of the box. V4WM fixed all my V4 pose problems.

TY2, Miki, Anastasia and Tyler are great figures that are a joy to work with, but with very limited support.

Wardrobe Wizard works really well for getting clothes to fit.

I've started using the Morph Tool to make my own character morphs. It's easier than I thought, I'm pleased with the results, and it's quite good fun. The Face Room is also quite useful.

I wish there was an easy way of moving textures from figure to figure.

If SM really wanted their figures to "take off", they should make some free merchant resource skin textures for them.
