Is there any big difference between Molecule and Frozen?
As I see it, they are both Quark copies without the early miner bias. They have similar difficulties too (2000 and 3000) so both are pretty popular.
Anything I am missing here?
I watch @ every CPU coin that pops out. There is a difference between those coins.
MOL was fail-launched and this coin was supposed to be premined. But dev failed at it, so he probably won't put much effort into further development. And if there was one unexpected fork we may see another after some update. I don't see any future here.
Frozen feels much stronger to me, it has its community and people eager to buy Fz now. I think this coin will hit an exchange in a matter of days/weeks. I personally have chosen this one over all available CPU coins.
