NoiseMaker has a ton of features and a wide range on every control for such a straightforward little synth and is a very power virtual analoger. That said I just don't like the sounds it makes. I sometimes will use it for a deep bass sound or something, but TAL's Elektro is a cooler virtual analog bass machine capable of the same gut punch, grit and detuney goodness as NoiseMaker. Also, the GUI for this synth has too many collapsible windows. Its hard to see all your parameters on screen. The simpler architecture of Elektro doesn't make it any less powerful for the tasks I employ both of these plugins for. NoiseMaker is free, so you might as well download it. Maybe you will like it better than I do.
I use this to make some of my more basic synths. You're not going to get any extreme filter modulations or what have you, but you can get some pretty decent lead or pad tones, especially if you layer some overdrive onto it.
It's a great little synth for a music producer who is looking for a good free vst. It's good, but it's not sylenth, massive, or serum. Y'know?
