Army Painter questions

[Urauloth]

I've never used any Army Painter products (although I plan on changing that in the near future as their sprays look fantastic) but I'm very interested in their gunmetal in particular as it looks like it's purpose-built to fill the void left by boltgun metal (rip) and I'm wondering if anyone's used it yet and if so how it stacks up?

 

And less specifically, what are their paints like in general? I've seen a few people recommend them and seen a favourable review, but I wanted some input from people currently using them. I'm more interested in finish, drytime, flow and consistency than value for money (which I understand is great compared to GW)

 

Thanks in advance~
