Reply to 2 chanle mixer vs 4 with 2 tech 12s and oxygen 8

I posted about this a while ago but couldn't find it to check answers, couldnt evenfind it in my email, ne ways... First off is there a better controller to add two decks to my tech 1210s than the oxygen 8? Second, I'm planing on using my rane ttm56 with a kontrol x1... Would it be easier to mix all four channles with say a djm 600 or the new allen and heath mixer? I forget what the mapping for the oxygen 8 dose exactly, more specifically how you fade the volume up and down... Any ways id prefer to keep a 2 channle battle mixer with the x1... But im open to ideas. As far as the oxygen 8 it seems dope, I mainly want my second controller for laying down loops and juggling, maybe cool white noise builds ive seen tutorials on, and other effects stuff as well as mashing up with decks a and b. I'm bookmarking this thread so il definitely get any responses this time. Thank you in advance.
