I think UltraNova is like Korg R-3, that is not so cool - the sound is dull and plastic.
VA devices like Clavia Nord Lead or Access Virus are much better and they can be a rivals to analog synths like Moog, but cheap things like UltraNova or R3 will not compare.
And I think that all these embedded virtual emulated fx processors are evil
