Well, you should try Micheles's, at least the demo. Its true metaballs, there are some things that I liked. I'm not a polygonizer pro, but I think there are some simple things that are better on MetaballsV3 for simple metaballs, haven't tried it on particles or creating huge meshes, although the smooth result seamed more stable. When you create a metaball the mesh created is the exact size of the control null and you can scale it in different axes for example to deform your metaball. In polygonizer the only way I have found to create a metaball is creating a null and polygonize it, if you scale the null in just one axes nothing happens, and the null is always a different size from the mesh. This is important if you are animating, at least for me it is.
And metapaint is great! It simulates a liquid type of motion on the metaballs.
I hope Michele continues to update it, its up to us.
