Juho, I'd seriously consider a dedicated module of some sort. I used Battery for a year and a bit and went through loads of samples but it never really sounded professional and sounded like a computer was making it.
I got a Boss DR880 box and the quallity of the samples on it beat any software / drum library I had and they sit in the mix perfectly - something I found hard to do on Battery. It's got lots of very realistic snares and lovely, crisp cymbals.
Have listen to the demo:
