well first there are many layers so if you wanna take the time and make it sound more human you can but thats not as big a deal. mainly they are just better recorded and sound much more real the the fruitly loop drums if you like the drums in fl studio use them but more than likely the best soudns will be nskit(when i used to program my drums i used ns kit but i used the one of the kicks from fruity loops) the part where fruity loops lacks the most is in cymbals, and seeing how nskit is free it doesnt really hurt to go ahead and get the extra variety but with a little eq the nskit can sound really good for any application
