How would you compare these cameras?

Sony Alpha 330

or

Nikon D3000

I'm leaning more toward the Nikon.

How would you compare the two, how is the other one better, etc. What are the specs of each and why are they better.

I wouldn't compare them but I would suggest the Nikon is a better choice.

Personlally i would go for the nikon. Reason being abetter choice of lenses

Nikon D3000 has 80% more lenses available. The D3000 has a slight edge (0.1 f-stops) in low noise, high ISO performance. Sony DSLR-A330 Autofocuses with all autofocus lenses. It Helps eliminate blur caused by small camera movements
