Reply to Whats best for Dubstep the NS6 or the NS7?

I've been saving up money to get one but I'm not sure which will fit Dubstep the most, it looks like the NS6 has a lot more effects and features then the NS7. But I seen people making Dubstep with the NS7 and its just as good as the NS6, one of the reasons I am stuck between the two is that the NS6 is smaller and compact and the NS7 has the turning wheels so its like its really playing and it seems like it would help out a lot with scratching and the timing and accuracy of doing it. But the NS6's fancy lights and about 3 times more buttons and sliders seems like it would fit... Btw to clear this up I am a noob at this, I worked with FL Studio and made my own and was hoping they could help me and even if not I still want them for mixing songs to. Thanks for reading
