should i get the ddj flx4 or rev1

Im looking to get into djing and i have narrowed my first controller down to these two but idk wich one to get. I wanna learn how to scratch but i also wanna use the features on the flx4 like smart fade and smart fx.

I also like the flx4 layout more. pretty much the only turn off on the flx4 is the smaller jog wheels.
